BLOWN UP! 1959 Dodge 315 Hemi Engine Teardown And Inspection (And How To Un-Seize A Rusty Engine)
HTML-код
- Опубликовано: 29 сен 2024
- The good news? This engine was as cheap as cheap could be. (Thanks Mark!) The not so good news? The hole in the oil pan... I had a genius plan of firing this engine up on the floor after I got its home. Unfortunately, the universe had other ideas. So today, we're going to tear down this not-quite-baby-Hemi 315 and see what's what. Being a very, very late original Hemi, there's a lot of interesting stuff to learn here.
ATTENTION COMMENTERS! I am fully aware that Hot Heads is the spot for early Hemi parts. In fact, they are the source I checked hoping to find .030/.030 bearings for this unit - but they don’t exist. We now return to our regularly scheduled programming.
their is that thar thang called welding the crank if one can find a shop with their head on a bit straight
@@overbuiltautomotive1299 Yeah, see the thing is though, I've had cranks welded (with only one bad journal) and I happen to know what that costs...
Would like to see that hemi run again.
Maybe try Kanter Auto Parts, or Egge Machine
Hart's in Cecil Ohio welds up and grinds cast cranks at a reasonable price... and found me high priced bearings at a low price... and many places do forged cranks...
Your sarcastic wit is just fine
Yeah, with a pinch of need thrown in. I like it too.
You are quite funny and amusing, in a quirky kind of way. Dont listen to the negative people.
Keep on building your niche! MOPAR or no car.
DDG has the key elements that make a car YT channel successful. 1.Knowledge 2. Good narration/explanation 3. Clear watchable video 4. HUMOR. As a fellow weisenheimer I can assure you sir you are indeed funny. Or in DDG terms maybe you are un unfunny !?
Something like that 😅 you always seem to find the humor where I do. Many thanks for that.
What an interesting autopsy...I mean engine tear down.
What’s funny about that is my original title had “autopsy” in it, but I forgot and changed it. Lol.
Hi , at 15 ( '65 ) I helped a handicapped neighbor pull the heads on his '54 New Yorker . Fun fun fun , like the Beach Boys hit at the time ! Take care , Neil 👍👍👍👍👍👍👍👍👍👍👍👍👍
Must be the rarest Hemi ever. I never heard of a 315 Hemi.
I mean, not really that rare. Standard Dodge Hemi in 1956. There was also a poly version of the same engine (note that this engine, despite being number designated as an original Hemi, has poly pistons.) Powered the ‘56 D500. Also used in truck, bus, and industrial applications 56-59ish. May have still been in use in some cars for ‘57, I’m unclear on that, but there was one larger size at the end - 325. That would be the rarer one.
I have a 57 Dodge D500 325 hemi, a 57 DeSoto Firesweep 325 poly (which is actually a Dodge motor), a 56 315 2v Dodge poly, a 56 315 2v truck hemi, two 56 DeSoto 2v 330 hemi, one 341 DeSoto 4v hemi. D500 is rebuilt, not for sale and keeping the 325 DeSoto short block for insurance, but not sure I will ever get to the 315 hemi, 315 poly or the 3 Desoto hemis. Located in MN.
Dang. I could use one or more of those… but I’m a long way from MN.
Breathe new life into that Hemi!
Luv watching engine tear downs alot ... Keep up the good videos
AWESOME vid....nice break down from a broken HEMI... PS: you are funny. MOPAR 4 EVER.
Thumbs up man! I'll watch everything you got to show. Ur a real car guy just doing ur thing. Please just stay the same.
Thank you! I won't be changing. Haha.
The rods from the Polysphere block will adapt to this operation.
So will the crank, and the block - but first I’d have to find one of those.
Try hotheads in Mt airy n.c. you look almost local but, they are the expert's on these
Oh I’m well familiar with them. But I’m far from local.
I did enjoy your video . Thank you .
It's easy to get confused about these early Chrysler V8 engines. Especially the "poly" and "hemi" engines. The Hemi engines were made in single and dual rocker configurations. The cylinder heads and intake manifolds interchenge with the correct deck height blocks. The Poly engines are "semi" hemi animals. almost nothing interchanges with the Hemi engines.
Uh… no. I guess it is easy to get confused, because you seem to be. Hemis were all dual rocker engines. The single rocker versions are what we know as Poly engines. The 50s Chrysler and Dodge Poly engines are literally a dual rocker “Hemi” bottom end with different pistons, and the single rocker heads bolted on top. Yes, there are short deck and tall deck blocks and heads - essentially split between 51-56ish (56 was tall deck for Dodge, but not Chrysler) and 57+. Tall and short deck used the same intake manifolds - and so did the polys. Now, the A engine poly that is based on the DeSoto Hemi is a different case. I’ve spent a lot of time talking about the evolution of that engine into the LA we all know and love.
Got you, what I was refering to is that most people think of Poly engines as the Polysphere engines of the late 50's and 60's. The A-engine. Very little, including the manifolds interchange with the Spitfire and Hemi engines of the 50's@@DeadDodgeGarage
Rebuild the hemi and put it in an A body and smoke tires.
Hey Man where you at? I got a early Big Block 400 that is mostly complete that would be cheap and id love see somebody use it.
I’m in Western Washington. If you are anywhere near to here, shoot me an email! DeadDodgeGarage@gmail.com
I want to make that rod into a shifter handle for the blown coronet for fun and good conversation
Well it’s definitely available! Haha.
Put in the trunk of my coronet please
Those heads just scream Power! Well, they scream something.
Head bolts smell is like no other.
@20:55 that actually was funny😂😂😂 I think people like self deprecating Humor. Just a tip for being funny. You make fun of you before they do, saves them work and people always like work savers. 😂😂😂 we are one in the same because I love LA and Magnum engines myself and i went off topic and am talking in a circle so i have no idea what an LA engine obsession of mine has to do with humor. 😂😂😂
I mean that's kind of my whole thing. Haha. I personally think the only humor is the self deprecating kind. Some people just don't get it... and that's fine.
A body swapped 1st gen Hemi.Yes.
You're in WASHINGTON! Thats either Aberdeen or Hoquiam, right? Im in Clallam Bay.
Yes, Aberdeen. Haha. Good eye. I sold and delivered a ‘74 Dart up there in Clallam Bay a year and a half ago or so.
It doesn’t have to do with this video but do you have a preference in add on gauges between mechanical and electric gauges? I know mechanical used to be more accurate, but is it still that way? I know electric are easier to run.
Electronic are definitely easier to deal with. I don’t think it matters that much. Historically I have preferred mechanical, but that probably means they were a few bucks cheaper.
@@DeadDodgeGarage thank you Jamie. I appreciate your responses.
Jamie is to Mopars like Lil Nas X is to shoes. A little bit of blood goes into every project. 😁
😅
What is the VIN on a real 71 340 Duster, one for sale near me for a good price and is being sold as a true 340 car but I just want to make sure it's no a 225 or 318 car.
The fifth digit of the VIN will be H on a 340 car.
@DeadDodgeGarage Hmmm okay good to know 5th digit is a C so guessing not a real 340 car
@@forterierocks Nooope... C indicates 225 slant six.
Neat!
2nd comment. If you can't have it re-built, you got an excellent door stop...... 😔
With ruined bores at the .030 size, and a ruined crank already .020/.020… it’s going to be complicated. But it would make one hell of a table.
You had me laughing LOL
👍🏼
Growing up in north Seattle during the cold war years of the 60's, in North Acres Park there was tower with an air raid siren that would be tested every now and then. A badge of courage for us kids was the claim we had gotten past the barrier and climbed the tower. I did it once, and low there was a Chrysler FirePower hemi powering the siren, no doubt one of those industrial engines. I was a young car crazed kid and knew what it was.
Back in 1950s our farmer neighbor had Chrysler Fire Power Hemi powering their irrigation pump around the clock in summer... no mufflers on it...
I've always had a hankering for a 41 willys with a early hemi! After watching this video I'll be building one in my head for the rest of the day!😊👍
I definitely want to do some kind of period race machine with one. It would be neat.
I remember that movie! Small town corrupt sheriff and car dealer and son race a cross country drag racer.
I have a 1959 Dodge 325 Hemi. The bores were all bad so I sleeved all 8 bores and made it into a 315. I can get 315 pistons, 325'5 are special order.
My Hemi also has the non-adjustable rockers. I suspect that Dodge went to hydraulic lifters for the last couple of years in the truck line but kept the rocker covers. The new LA 318 oil pump will fit with an adapter and longer drive shaft. The drive gear is the same. I also machined the water pump housing to take a B block water pump. The heads have tiny valve heads but 7/16 stems. The exhaust valves were sodium filled for cooling.
I found that the valves out of I believe a 2.3 liter Ford will fit if you replace the huge valve guides with 11/32 ID units. I made my own. I also installed hardened valve seats. Cam shafts are not available. At least not for a reasonable cost. Regrinding the cam and adjustable push rods unless you can locate some adjustable rockers. I have seem some examples of people drilling and tapping the rockers. They get very thin wall between the screw and outside of the rockers.
Have fun
I like teardown videos. I grew up near Detroit and would often hear the phrase “rebuild the engine.” Now I can watch it happen, have it explained, and not freeze my ass off. My childhood memories of auto repair all take place in winter on cold concrete floors in a small unheated garage.
I’m very aware of how unheated my garage is currently… either way, happy to help. Haha.
🇺🇸👍 Any Hemi is worth saving, if your check book can handle it, if not pass it on to someone’s that can 👍
Yep! I’m weighing my options there. If I can find a crank and pistons, plus rebuild parts, and not have to take out a second mortgage… we’ll see!
Don’t listen to what others say! I find your wit and sense of humor wonderful. I appreciate all the detailed information you offer. Good job bud!
I think the sardonic side comments make the videos much more entertaining while I learn so much about engines and cars I’ll never own, Very cool
What a fun trip down Trivia Lane. I really enjoy suprise filled tear downs, and your knowledgeable humor is most entertaining. Great stuff!
I like seeing teardowns, especially carnage for some reason... If there is a chance to make that Hemi, I'd definitely watch the rebuild, I'm sure you could find a car to put it in.
Oh yeah. A car won’t be a problem. Haha.
Yeah, I am interested to see a Dodge Hemi project. They’ve got the instantly recognizable Hemi good looks, and their much smaller size opens them up to being used in some sort of rod or boat where it’s going to be highly visible but space is limited. There used to be a rod in my area running a Red Ram with a 471 blower driven by a bunch of common V belts, very cool.
My first car was a 1971 VH Aussie Charger with the Aussie built Hemi 6. That was a fun car which also taught me to fix cars because I was constantly fixing things, Your videos are the next best thing to owning one, What is left here in Australia is mostly price prohibitive. Cheers.
You already know i want to see you do something with this 315. Its very much like my 56 D500.....sans the big valves, solid lift cam, dual point distributor and 4bbl wcfb. That said, a road toad would be perfect for one of these as would the 63 Valiant. Wildcat has an abundance of road toads so maybe a joint build? He might also have a connection for a detter 30:10 baby hemi. I think you already knew i would love to see an LA hemi. Probably not worth the eventual gains. But the amazing factor would be exponential.
It’s almost certainly not worth the trouble in terms of power, but I really think it can be done, despite the nay saying of the forum trolls. I just want to see for myself.
You asked for this, so here goes. Brace yourself.
If you want to rebuild this engine & help to keep costs under control, then go find a 1957 Dodge junker. The D500 Hemi was a "tick the box & pay the extra", OPTION-ONLY in 1956 & '57 & with only about 17,500 sold new, in1957, after close to 67 years later they are now quite rare.
However, the standard engine in '57 was the 325 Poly, [semi Hemi] which is essentially the same as the Hemi below the head gasket. These should not be too hard to find as squillions were made & with the current demand for these engines, should be quite cheap. So find a good junk one & you are well on your way. The engine No. prefix for these in '57 is KDS, & they were also used in some DeSoto models, Quick & easy to identify. you might as well use the 1957 KDS 325 engine, with an extra 10 cubes for free over the '56 315 cube engine.
If your block can be saved, then just use the parts you need, if not, then you have a donor block. Win win.
The Poly version used EXACTLY the same block casting, it was machined for the Hemi pushrods anyway, same crank, same rods & pretty much everything else. The Poly short block needs only Hemi pistons & cam profile & BINGO, you have your rebuild well on its way, & lets face it, you're up for a set of pistons & a cam replacement or regrind anyway. Even the gasket set is the same including head & inlet gaskets. The exhaust & rocker cover gaskets are Hemi only.
I have two 325 D500 engines here in Australia with one 'gurked' [ frost split block & seized] but I have a totally bare KDS 325 Poly block under the bench, so I can rebuild it. Instead, I am rebuilding the second, but much better engine. The damaged one is a future project.
Since you are an LA man, as was I, here's a tip. The LA bearing caps will fit these 1956 & '57 engines, but just use the LA rear main cap. [Line hone required] The stock LA pump bolts right up using the stock LA drive shaft & gear. No adapter required That's what I have done with mine. Check the bearing locating tang position. It may be on the wrong side of the cap. Mine was not, so, good to go.
Use Hemi/Poly main bearings as LA's use a wider center/thrust bearing. A little machining on the center LA cap allows the use of a full set of LA caps with the Dodge Hemi/Poly bearings. Good to know if upgrading with 318/3 heavy duty truck, or 340 HiPerf caps. These are, apparently, made from a higher grade iron.
Again, to keep costs under control, use the passenger car water pump & housing from the donor Poly engine to reposition the pump lower & to do away with the truck engine mount in your application. Ah yes, the Poly donor engine, the gift that keeps on giving. Oh yeah, you need an oil pan too, Poly is the same.
Also, TR Waters does [or did] a converted LA timing case for the Dodge Hemi. Again, with a readily available LA water pump, this could be an option.
The Hemi/Poly passenger engine did NOT come with a harmonic balancer, but you can use a good LA one [recommended] by broaching the keyway to Hemi size, or use a stepped key. [TR Waters again]
For a cost effective exhaust upgrade, use two left side Hemi passenger car exhaust manifolds Any model from 1953 onwards, & you have two center dump 'Rams Horn' type exhausts, but your alternator will need repositioning. [Don't waste your time with the generator] Again, a cheap upgrade, particularly in a street rod. These shouldn't be too difficult to find.
Surely you know by now all of the wonderful goodies on offer from Hot Heads Research & Racing for these engines, & of course, I sold my soul to the devil & bought ALL the good stuff for my engine. My wallet is on life support.
The dimpled rocker covers were carried over from 1956 when some 315's came with solid lifters. Both of my 1957 D500's came with dimpled rocker covers.
ANY LA distributor, stock or aftermarket, can be used with a simple shaft extension. [Straight drop in for the earlier 241Hemi or 270 Hemi & Poly engines] By now it's obvious that anyone that has a good relationship with an old established junkyard, & a whole bunch of good/used LA junk engines laying around can rebuild & upgrade his Hemi at a reasonable cost but you need a serviceable junk donor Poly motor for the crank, rods & maybe even the block if the costs are to be kept under control
These rare & beautiful early Dodge Hemi engines are a true National treasure & a 325 Hemi was used in the winning '32 Roadster in last year's LA Roadster show. It used alloy heads that were made for this car & I desperately, desperately want some. My '33 Dodge Coupe neeeeeds them.
Oh don’t worry. I’m well aware of the Hemi/Poly relationship. I have done much reading on this over the years, but have been brushing up after acquiring this specimen. I realized today that not only do I know where a perfect Poly donor is, I know the perfect car to put it in when I’m done… I’ve also spent a lot of time over the last week perusing the wares on Hot Heads’ site. I don’t have the budget for all of this right now… but I sure have some ideas.
@@DeadDodgeGarage The costs can be a bit high, particularly when compared to arsehole engines [everyone has one] like Chevvalay's. Take pity on a poor ole Aussie who not only has to face the unfortunate exchange rate, but also the horrid freight costs along with a 10% tax on arrival. My engine has ben a 20 year project, starting with the 1-1/2 years spent looking for one, another year getting it home only to find a frost split in the block. I sourced a replacement block, but my spirit was broken. I had however bought all the rebuild engine parts from Florida [ two sets of bearings, pistons & just about everything I might need.]I now have enough engine parts to build the both engines. The fire was relit when I found another core about 2 years ago that cost over $6kAU landed at my driveway. This is a good core & is being rebuilt now. The final cost for a fresh/new Hot Rod engine with ALL the bling? I shut my eyes & see a black hole into which I just keep throwing money which is why this has been a project spanning over a generation. If I lived in the US I could have done it all MUCH quicker & for far far less. Such is life.
Love your Hemi, treasure it & do not treat it badly, it may be the lasting legacy that you need.
They can be rebuilt properly on a budget [that's a relative term] but don't let a few dollars make you shy away from this one.
@@KB10GL I decided decades ago I would have a Hemi, and also being in OZ i was behind the 8 ball Until I found a guy in SA called Jack who had a 354 for sale. I bought it unseen and got a 331 bored to 354,Long block etc. But it has 13-1 pistons, twin WCFB's on a special manifold( made for the Carlkiekafer racers!!) Isky 4HHH cam ,roller tappets etc and fully Ported heads.It was allegedly a spare engine for someones Bonneville attempt. . I built it up and ran it once on lake Gairdner ,being the 1st early Hemi to run on the salt in OZ. I ran into a bit of difficulty and sold it to a Rodder on the gold coast. I was Hot Heads first overseas customer > I still have his hand written catalogue!.😁😁 While mucking about with that engine I met a lot of the old guys from the 60's who had run Hemis at the drags and even saw pics of a long block 331 in a Austin Healy! There were quite a few imported by guys like Diablo motors in Sydney. and many must still be stacked way in sheds around oZ.
@@Mercmad So good to hear your story. Yes, there are a surprising number of Chrysler Hemi engines here in Australia, & a a 1956 354 cube version is my preference, but not so many Dodge & DeSoto engines. Of the four 325 Dodge Hemi engines that I know of over here, one is in a Model A Bucket in Renmark S.A., another in a 1933 Dodge Commercial Sedan in Adelaide & I have the other two in NSW. I hope that the alloy heads that may become avail in the US actually turn up as they would make life complete. OK, a bit of overexc9tement here, but they would be nice.
There are at least six 241 engines that I know of & probably a couple of 270 & 325 Hemi engines in Oz that I haven't heard of yet.
My van is now youtube famous. Thanks again for the help buddy.
Those relics are interesting....you may want to look at the casting numbers on the crank ...they used the industrial motors on test stands and generators and agricultural pumps where the firing order is 180° off....good content and thanks.
I was imagining the smell JUST as you mentioned it.
Those piston skirts are knurled. That's a lost art (and machine) from the mid 20th century. I worked in a bunch of different machine shops back in the day and only recall one that had a piston knurler. Generally, the service was provided to cheapskates who wanted to do a shade tree "rebuild" consisting of rings and rod bearings. If the bores were a bit worn, a hard knurl could add up to about 10 thousandths to the skirt diameter. This type of "rings and rods" job was good for about 8-10 thousand more miles. We sold the kits to a LOT of used car lots. Some of the old guys in the shops maintained that knurling held oil better and was used on some racing engines and for some blueprinting jobs, but in my experience, it was primarily used for hack rebuilds. I'm guessing that the 30 over rebuild didn't last long under hard use and at some point it got another re-ring and knurl job, during which someone overtorqued a rod bolt, which eventually let go.
Yep, a couple other people mentioned the knurling. I noticed it but didn’t take any time to say so. I bet you’re right! One thing is for sure, this thing had a hard life and has absolutely been “overhauled” multiple times.
That is a god awfully expensive and difficult to source build you are proposing. The first part of any build has to be a budget estimate, then double it, then figure out if the divorce is worth it. This was amusing, thanks.
My wife is cool so I don’t have to worry about that. There are six engine builds in progress in the shop right now. And doing the build labor and prep myself sure saves a lot of money. I am looking for a poly bottom end to fix everything wrong with this. But we’ll see.
If you live around oil wells I would suspect that motor had been ran on casing head gasoline,its free but knocks like hell and beats rod bearings out. Also i noticed a couple knurled pistons which is super old school patch for bad piston to wall clearance and only being on a couple my money is on the machinist had a slip when going 30 over.
Noticed the knurling, very interesting. No oil wells anywhere near to here - but who knows where the engine came from.
19:42 looks like the no.3 piston is turned 90 degrees. Oh, 21:19 yup, turned sideways, neat trick.
I was pretty impressed with that.
I enjoy your humor and find you very entertaining... and I learn stuff. So I subbed and belled and all that good stuff. See you next time.
Thank you!
I agree.
I want one of those train cars every time I drive by
Big same. I don’t know what I would do with it. Wait, yes I do.
Also, ignore the haters - you're funny enough....
Don't pay the heathens with no sense of humor a bit of attention.
Haters,
BTW, Haters make you money. So the more vitriol the Ford guys spew the more I will suggest they LS swap it. The more gm guys detract the more coyote swap 55 BelAirs I will suggest.😮😊😅
Oh I’m well aware. Haha. Friggin Ford guys…
Very entertaining, no matter what the experts say. Another good rust breaker is MEK and dexron and all the rest you mentioned.
I personally find you quite amusing, and I have been a Mopar junkie as long as I can remember. Making your videos very entertaining. My first car was a 64 Plymouth Savoy with a poly that must have been built on a Wednesday. It was dangerously fast for a 17 year old, and would float the valves in high gear. Apparently fast enough to out run the boys in blue, that I didn't even know were trying to stop me! If I had any notion that I could have installed a set of hemi heads I would have been ecstatic!
I like those later poly engines too (although I can’t say I’ve ever seen one that ran like a scalded cat…) but they are not the same as the earlier Dodge and Chrysler Polys that were a head swap away from Hemi glory. However, I still think it’s possible, and I am going to try to gather some DeSoto heads to prove the theory.
@@DeadDodgeGarage I look forward to it. I am always open to learning, not being an expert in any way shape or form.
I like teardowns
I really enjoyed this video, and would like to see more teardowns! I'd also like to see you get the Hemi running again, I do wonder what will be harder getting the parts, or getting it able to run again. I also want to say I enjoy your humor/ sarcasm! Thanks for taking the time to show us.
I’m on the lookout for parts to make that happen. Crossing my fingers. Thanks!
That was fun as hell to watch and listen to. Earned a sub. Also, engine carnage good. 😏 I've got a 53 Packard straight 8 to unstick sometime this summer.
Thanks for joining! And good luck.
@@DeadDodgeGarage - Thx. Always been partial to Mopars, the leaning tower of power and semi-hemi polyheads but got priced out.
I would definitely like to see this hemi come to life, but then what to put it in, that's a great question. I have a special interest in the early Dodge hemis because there is a possibility that my 56 pickup might have come with one originally. Or it might have been a poly head, but probably the same block as this. It has the original V8 badge on the hood so I know it was one or the other. The funny thing is that it had a 318 poly/4 speed trans from a 60s Dodge pickup when I bought it, and because the previous owner had modified things to make the 318 fit, I was able to swap in a 318 small block with very little trouble.
Also, my dad once had a 58 Dodge Coronet with a poly head engine that might have been the same block as this hemi. I think it was a 325, but I do know it had the poly heads.
Very cool. Right, either way, it’s the same bottom end essentially. Yep - that would be the 325 poly in the Coronet.
I enjoy your humor very much so. Keep givin err.
If making a mess of your garage is a super power, then you are the master of the universe my friend!
They also used the industrial Hemi in air raid sirens. Those are cool videos look up Chrysler air raid sirens.😎
I’m hip to that. I’ve seen a video of a guy running one in his garage. I think those were powered by the big Chrysler engine though.
@@DeadDodgeGarageI'm not sure which hemi they used but it was sure loud.
Man that's a neat engine. I looked a gift horse in the butt once, I'm still haunted by the experience.
I think that’s what therapy is for 😅
@@DeadDodgeGarage😂😂
In all seriousness man, would love to see something down with that thing if possible. I mean, how cool would an early Hemi powered A body be?!
Thats is the funniest thing I've read today. Awesome 😆
Thats is the funniest thing I've read today. Awesome 😆
My high school auto shop (ca 1974) had a Red Ram Hemi. I still remember all those burnt valves
Possible quote from 1976: Hey buddy, hold my Lucky Lager and my cig while I disconnect this governor thingamajig... that way you can rev it to the moon. I bet this is how Smoky Yunick got started. Naw you don't need to warm the engine up. Crank up that Thin Lizzy 8 track and watch this....
Those were used quite often for irrigation pumps, likely in your area. And at high RPM for long periods . Still, a very cool engine, block is probably OK.,,,Keep at it,,,,,Izzy,,,
You don't get to see many engines like this these days. Very interesting stuff dude!
1,Focus is overrated, 2, every thing IS awesome. 3, just methinks but im guessin MOST of those that keep tellin ya your wrong have'nt spent 20+yrs pullin the pigs apart an gettin em goin (by ear, i might add) butt rarther get their "knoledge' from the keyboard. Probd cant tune them either . Luv ya work . Cheers
Great vid. My connex full of Pentastar power plants of the past has a couple of baby hemis thst i tore down a few years back, a 241 and a 270. Came across a 331 short block still in a 55 New Yorker at my local pick-a-part for 75 bucks about 4 years ago. A friend sold me a pair of heads he had stashed since the mid 80s. Then i really wanted to find a Desoto hemi, also. 2 years ago a picked up a 57 Firedome that i had watched in a field for 25 years. Has a 341. Got it running and cant bring myself to seperate it from the car. Its a great sounding yard ornament. Looks great going to the gas station, too.
I couldn’t bring myself to pull that, either. I had to pull the 331 I had from the 55k New Yorker I had just gotten it running in. That was the deal for the car, and I thought I could get another one easily. Not so much…
Great video and commentary on the old 392 273 hemi. Would love to see you resurrect that if possible or as you mentioned one of the early De Soto firepower hemi. I had one of these years ago, but never had the time to work on it and ended up getting rid of it, which I regret.
interesting video -- I would love to see that engine run again. I am always down with bringing old engines back to life. My old '55 210 has a 235 "Stovebolt" six in it. I had to replace the timing gears last year -- quite a chore.
I found one of these in a old forklift when I was a kid. The forklift owner eventually replaced it with SBC. I got my hands on it thinking I would build a 10 second street rod with it. Once I sobered up, I noticed how small the crank was compared to the power plant of choice in 1979, the BBC. It was going to cost a fortune to build, and the performance potential to cost ratio just didn't add up. I let a Mopar head friend of mine have it. As far as I know it's still sitting on the floor of his parents garage.
Hemi resurrection please!
I think your funny ha ha. Ever seen Slingblade the movie. Yeah keep being funny. We should get rainbow socks ha ha. Keep up the good work.
This one is so far gone, even Dr. Frankenstein couldn't jolt it back to life. But, hey, anything is possible with a large caliber parts cannon. I'm for hooking it up to a tall radio antenna during a strong electrical storm. That ought to jump start it.
Hope you can use this - too cool( I couldn't wait until the end to comment).
Okay, now my brain hurts! Thanks Jamie.😂 However, I did enjoy seeing the carnage! Yikes!
Bet that engine made a hell of a noise when it became a counterweight
Wish I could’ve heard it…
Yeah, get it going again, and then we'll throw it in the 1959 Facel Vega that I can TOTALLY afford. 😏
I have a 57 Imperial 392 and a 59 Dodge 315 both complete sitting in my shed. I got both of them back in the 70's and have started them once a year since then. Some day maybe I'll get around to putting them in my two 32 ford roadsters just for kicks. Thanks for the great video.
Awesome!
Brother hood cool working on a old hemi hope you rebuild it anyway im looking for a pair of poly heads I can put on my spare 313 block
The Piston you showed the pitted crown has been resized by knurling. That's really old time (1920-30's) engine repairs. So it could have been rebored,used and worn,rebuilt again and put back into surface when a stretched rod bolt broke.
I ran an LA oil pump and distributor in my 331.
Do you have a 325 Dodge you could use the heads on? You will need a set of pistons as you said,the valave reliefs are in the wrong place on the polys'.
Not yet… but I’m keeping an eye out for one. I do know where a dodge poly is, but I think it’s an earlier short deck engine.
This might have already been commented but, none of the Chrysler products (new) had a HEMI from 1959 to 1963. '392 was last in '58 and the '426 came out in '64. The '315 was in 1956. The '315 would be a nice engine for about 180 bHp.....I believe "Waylon Wires Old Iron" has one with the transmission, and it ran for him hanging from a lift. Maybe, after viewing for a few minutes (14, to be exact)...I should say this is a unique engine....Not shown in details in Wikipedia.....as a truck/bus engine.
Yeah… we can’t take Wikipedia’s word as gospel on this one. I’ll go ahead and trust Hot Heads - the Hemi experts - who have this exact head casting number listed at the very end of their chart, as the very last early Hemi head, and specifically listed as being truck or industrial. It is the only part number of its type, leading me to believe that this head casting was developed much later than the rest of them. The stamped ID number on this engine is found on the early Hemi list of engine numbers as TRUCK / BUS. They could apparently be found in a heavy duty chassis - not your standard one ton pickup - in 1959. And if you want to ignore all of the rest of that information, well, the July 1958 casting date tells us everything we need to know. Given the lead time generally found between casting dates and engine build dates, it’s highly unlikely this engine could have made it into a 1958 model year vehicle. Are you aware that all big block production stopped in 1978? Are you also aware that they could be found in trucks and motorhomes into the early 80s? Same idea. Hopefully this makes sense.
Hi Jamie. I had a 273 that was fitted with 10:1 pistons, and a set of heads from a late 273 w/ 1.88" & 1.50" valves. It had a purple shaft and a 340 stock cast iron intake w/ Holly 600 and a curved Prestolite cast iron duel point distributer. I used the same exhaust manifolds that came with the 69 Dart Swinger, w/ 4speed & 3.55 suregrip. It weighed just under 3,000Lbs. I ran it pretty hard, and it was no slouch. It performed well. Well, for a 273 anyway. It was no 340 like the car had originally, but it was an interim engine while the 340 was being "freshened." I'd say it had at least twice as much punch as it had when it was pure stock w/ 2bbl carb and mild cam. So, I didn't catch what your 273 is going to do for you, but if you prep it right, it will be fun. Remember 273 was part of the early 60's Scat Pack and was rated at 235hp w/ a quad. My 340 was rated at 275hp, but we all know it made around 350hp stock with the Carter AVS. I hope yours does you well. ben/ michigan
I did a 273 video in which I discussed my plans. They aren’t too far off of what you built, but I am planning a few “modern” twists in the interest of high RPM performance - and an extra carburetor on top. This will be going in my early Barracuda drag car project, which I hope to get down around 2400 pounds or less.
Get it running! I have long been under the impression that the valve cover bumps were for high lift valve clearance in the letter car hemis, not particularly for rocker adjuster clearance, but maybe that one a the same thing. I’ve owned my 392 powered NYer since ‘78, and have a soft spot for all the 50’s hemis.
Yes, it's to clear the adjustable arms that are found in high performance or heavy duty engines. Someone else in the comments pointed out that the performance Dodge engine found in the D500 would also have them. Nice! The first one I owned was a '55 New Yorker. I really liked the car, but it was very rough, and I had to pull the 331 and give it back... It was a major bummer. I really want to own a '55 Chrysler C300 but it hasn't worked out just yet.
Another new subscriber and glad of it. Comment info can be gold. Lots to see here. Yeah, give Eric on I Do Cars a run for his teardown money. Those high top 273 pistons like you have scored what you need to make an S package engine? I have a stock rebuilt 273 to go in an A body with 4 speed. Bought an A-833 for a mate and it had the 18 spline input=Hemi application. Also have a 318 '64 poly to get together for an A hotrod Sportcoupe. It had 6 x .040 and 2 x .030 slugs in it, and lucky a mate had a set of .060 + rods. He also put me onto a P600 intake. Alan Fountain in Oz casts Edelbrock Poly V/C's without the script. Ordered 2 sets with 1 set goin on a Poly dual cab pickup import of a mates. Keep up the good content. Now to catch up on your earlier ones........
Nice! I love the Poly. Planning to do a build in the future. Yes, the domed pistons are the replacement equivalent to what was used in the Formula S Commando engine, or what Dodge called the Charger 273. Stock rebuilt 273 and 4 speed are my plan for my ‘67 Valiant in the near future. Hi po 273 is down the line for racing purposes. Good score on the Hemi trans… those are spendy units. Thanks for joining! I’ve got like 400 videos up (although around 80 of them are past live streams) so there is a lot to see. Haha.
I love hemis and I enjoyed the clip screw the naysayers and I love learning about those older engines 😂 I also see you are a musician as am I
Interesting. Thank you!
The Chrysler was the physically larger hemi, as it had a wider bore spacing. The Dodge and DeSoto engines both had the same bore spacing, and were finish machined in the same plant. From '52 - '54 they were only 6 cu inches apart. The Dodge was 270, and the DeSoto was 276.
That is not correct. The bore spacing on the Dodge engine is much smaller. I found numbers of 4.1875 for the Dodge and 4.3125 for the DeSoto. I’m not confident in those numbers, because the spacing on the DeSoto should match the A/LA series engines, but the number I’m seeing for those is 4.46. Whatever the case, the Dodge engine is smaller than the DeSoto. It’s pretty easy to see how little deck space there is between the bores in this 315. For such huge engines, in terms of architecture, they’re remarkably small.
I stood before the roar of the Chrysler Hemi at noon on Wednesdays all through my formative years. In fact the whole city of Seattle was drenched in the sound from city limits to city limits. The Hemi's powered the air-raid Bell Labratory "Victory" sirens. They were on huge steel towers across town. Two Hemis are still in place up on Phinney Ridge and another at the park on 145th & I-5. The loudest sirens ever made used for A-Bomb drills. 0 miles but plenty of hours.
Yep! Those things are cool. I’ve seen video of a guy running one in his garage.
I also have a 315 Dodge Hemi that came out of a 1 1/2 ton truck with about 50K miles. It was really clean when I got it. Long story short it now sits in my '32 Ford phaeton with a D500 camshaft and 3 Rochester 2 barrels. Lots of fun.
Outstanding!
My older brother's first car was a 1953 Dodge Coronet 2-door hardtop with a 241 Red Ram Hemi - and the Gyro-torque transmission. These were solid, dependable engines and ran well with decent mileage. The transmission was "interesting".. If at all possible, I think you should rebuild the little 315. Hot Heads in North Carolina also has parts for Dodge Hemis and may be able to help you. It is hard to imagine the level of neglect and mistreatment necessary to wear out this engine twice and blow it up once. I could understand the broken rod if the engine had been used on an irrigation pump, but not in anything that was actually run by an operator. If maintained, these engines are practically indestructible. The basic construction is so over-engineered that it was not uncommon to run 1,000 HP motors with the stock crank and rods for many seasons. The engine's appearance is so iconic that they are worth the space just to keep on display in the corner of the shop. I had an early Chrysler hemi engine once but let it set too long, the shed deteriorated, and the engine got exposed to the weather. Between the mice, fire ants, and water damage (both rust and ice), the engine block was toast. But the heads survived. They are still buried in a corner of my basement. The engine was a 1956 355, but the heads may be off an earlier 335. I would have to find them and check the casting numbers. If I remember correctly, the 335 head on the 355 was the hot set-up. The guy I got it from was from a family that owned a large salvage yard and he didn't believe in doing anything halfway...
Oh don’t worry, I’ve been perusing the Hot Heads catalog… and this can definitely be a display piece if that’s all it’s good for. But I’d prefer to get it to make smoke again some day if that is an option.
By Frankenstein: I mean why not take another 10 thou off that crank? Bore the block for 318 pistons and go 7:1 compression. Those values on those heads should be able to open a long way. How about a ridiculous cam. Top it off with a 671 blower or twin turbos and stuff unreasonable amounts of fuel down the pipes.
Because .030/.030 bearings do not exist. 318 bore would be huuuuge in this block… I’ve done the math on that one
Im guessing it was in a truck buses are usually well maintained. Ps your sense of humor is great
I have had 2 ‘67 Power Wagons in my front yard for over 12 years now. One is a parts truck and the other is ready to be put back together. I have the body painted and ready to put on. My health took a turn for the worse about that time and I retired as a Paramedic. I still am an Interventionist at a local high school. I just can’t get excited about getting it put back together. Oh, the engine is a rebuilt 383. I am not mechanically inclined.
Dang, that’s unfortunate. Sounds like a great project - but a big undertaking. I have a ‘64 here I am slowly getting back together. The body is total junk, but I do intend to use it offroad so that’s mostly ok.
I would definitely like to see more teardown videos. Lots of good info when you dissect an engine like that. It would also be cool to see you put a small block where it doesn't belong like a late 70's Dodge import. A Colt, Plymouth Arrow, or a D-50 would be super cool. I'm finally finishing up my '82 D-50 with a carbed magnum 5.2.
I agree. Nice! I'd definitely like to do something like that. People have suggested D50, K car, Colt, and more. The car kind of has to fall in my lap. I'm certainly not going to go looking for it. Haha.
I love tearing engines down to perform a little CSI: Mopar.
I used to have a 1957 dodge cornet d500 with a 325 Cid engine. I found this fascinating. Thinking about the damage and the valve cover, my guess it was not in a bus or truck but a stationary engine like an air compressor. I think those are the correct valve covers for that engine even though the valves are none adjustable. The water pump makes it clear it is not a passenger car engine. Such a cool engine and such a great video.
Right. Numbers on the block say truck/bus, and different paint color tells me covers are off of a different engine. Whatever it was in last, one thing is for sure - it has lived a long and interesting life…
