I can't WAIT to see him work his MAGIC on this beast😎 🤞 My first running car was a 70 Skylark w the 455 Stage 1 bored 40 over (462) a cam and a very large rejetted quadrajet I could pass everything but a gas station or a tire store. It was a torque monster to say the least. The first burnout twisted the driveshaft in half👍
I bought a 76 Delta 88 2 door royale from the 93yo original owner that had 63,000 and change miles this car is immaculate inside and out its grey with blue interior with a 455 goin on 3 months ago. I bought it to go big wheel racing the plan is to throw a turbo ls setup in it but last month just to playing around I put a Howard's cam & lifters,used edelbrock tourqer intake with a 750cfm double pumper I rebuilt my pawpaw has had for years, jegs brand hei distributor and some shorty headers with 3" exhaust with some fake flowmasters and turn downs I also welded the spider gears up and this big boat actually gets up and moves a little now! LoL and rips badass burnouts now over the winter its gonna get a turbo ls2 with rods and pistons and ls3 heads and some Rucci 26's I know alot of yall older guys are gonna hate it but its gonna be classy I already named it the u.s.s Alabama because the guy I got it from is a navy vet and its pretty close to battleship grey
The engine that GMC should have used. I had a one ton GMC with a 430 Buick in it and it was great. Who ever put the engine in there did a great job because everything looked like factory.
I pulled a barn find 455 olds apart once that had a head taken off after the previous owner vaporized a piston. There was a family of dead mice in the oil pan, preserved in their bath.
BTW, my first car with a '70 Skylark with a 350 and a quadrajet. 200hp factory. At 15 years old, my funds were limited so I did: Cap (see through!), rotor, ignition curve kit, plugs, yellow Accel wires, new Quardrajet (mixed up the plug wires then melted the old Quadrabog with starting fluid! LOL), Cal Custom 10" chrome air cleaner, painted the valve covers black krinkle. Got it all done and it was STILL a turd. Well, at least it still ran when I sold it and got to learn a bunch about cars.
My first car was a 69 Buick Riviera it was ovile bage color all original my grandmother got it in 71 with 5000miles on it!! Owned it till 1990 it had 70,000 miles on it when it was my first car!! Oh what smooth driving n riding car, it had a 455 with huge Quadrajet!! Flip the air cleaner lid on her n kick her down at 55mph sounded like a jet sucking air!!!
The reason the olds diesel sucked was the piston design. Detroit started the teardrop in the piston. Cummins also use this. Vw TDI also uses this. I wanna see an old gm- diesel “conversion” running direct cylinder injector with a teardrop piston. Probably run better than a powerchoke or duramax
Love the content. Keep it coming! I like how you get the engines to run for next to no money invested. It is refreshing to see this approach compared to some the automotive TV shows where they portray $4000 for a rebuild is no big deal.
If its in decent shape, doesn't have wiped or spun bearings, the pistons aren't broke, and no bent or burned valves, it will run.. it might smoke a bit, but it will run even if it was kinda stuck.. not super stuck, just kinda stuck. Compared to a $13k crate motor $4k is a bargain, but you can rebuild a Pontiac that makes 500-550hp/tq for $2200-$3000, that is forged pistons and rods, cam, lifters, bored .030, balanced, and having Butler or SD port the iron heads(that is the high end at $3k). Doing a Buick is a little more $$ but not bad. The trick is getting the machine work done and sourcing the rest of the parts yourself, and knowing what you need to get. Having a shop rebuild it for you will mean you get a stone stock engine for $6k. They have to mark up every piece they get, and if they get it from a local store, they will charge you list price for most of it.. which is quite a bit more money than what Summit, Jegs, Butler, KRE, SD, etc sell them for. With the Buick, Kenne Bell and TA are the place to go, and because not many are built and raced the stuff is going to cost a bit more.. but you are starting out with a good engine design that will fit anywhere a sbc will fit... and you get 455+ cubes from the start. The 455s make crazy torque starting at idle, and they carry it past 5000 easily, so no need for deep gears, big stalls, and all that mess. We put a 430 in a Vega back in the 80s.. it had a problem with breaking stock rear ends.. no idea why that might happen. It fit much better than the sbcs because the exhaust points downward in the BOP engines and that means you can get to the plugs easily and not burn wires.... among other improvements and better design features of the BOP engines over the chevy.. The cubes are lots of fun.
@@SweatyFatGuy Bet that Vega was fun. I read guys swapped Buick 350s in place of the Buick V6s in the H bodies like the Monza. I put a couple Chevy smog 350s in Monzas back when I was a teenager. I think you hit on the drawback of the Vegas and Monzas - the rear end. The Monza only came with a torque arm 7.5" like the 3rd / 4th gen Camaros. It was not the stoutest thing. Local guy ran low 10s in a NA 377 cid Spyder driving to the track. He put a Southside Machine kit in it with subframe connectors and ladder bars on a narrowed 12 bolt. I like your advice for building a motor. I only had one motor that I had machine work done on. Back in the early 2000s I bought a roller 351w motor from a van in a JY and just sat on it. A couple years ago I decided to finally put it in something and it is now in my 85 Mustang vert that used to have a CFI 302. My big mistake was not rotating the crank before I bought it. I found it rotated part of a revolution in each direction. Turns out a rod spun and the rod got all bent up on the big end. It took a small chip out of the bottom of a bore like you would make for a stroker. A guy I bought some parts from gave me a set of rods and a crankshaft from another 351w for free. I found a local machine shop that had a price list online. They had affordable prices and I had them thermally clean the block as it was all sludged up. They use some sort of flame setup to burn the engine block clean. They put in new cam bearings and freeze plugs. I wanted to just have the bores honed, but he discouraged that. I had them bore it 0.020 over and hone it. They also line honed the block, surfaced my heads, polished the crank and pressed my new pistons on the rods. I think I have about $500 in machine work. I don't think that is too bad and the engine runs good.
that Q-Jets is from a 1975 -79 Chevy or Caddy. only Chevy and Cadillac used side inlets for fuel lines. Buick, Old, Pontiac all used a front inlets. the throttle linkage was different on the carb depending on the year. if I remember correctly, Buick used a special 800cfm Qjet on these motors. the good news is that the M4MC and M4MV carbs were great performing carbs. In fact Edelbrock used it as the base design for the Performer RPM Qjet #1910. which is by far the best Qjet I have ever ran.
5:36. Buick Big Blocks were always interesting to me. If I recall correctly, some of them came from the factory with shaft mount rockers. Some of them have combustion chambers that resemble LS engines. Quench pads with open chambers. Others are just wide open chambers with no quench pad to speak of. Another neat feature about these engines is the way the exhaust ports extend out of the cylinder head without any coolant, then they go into those gusseted angular exhaust manifolds. And they had the distributor on the front. Way easier than a normal BBC. I always liked the black valve covers that said "Buick" on them, from the Nascar days. They had the turbo 6 on them. The Buick-powered indy cars in like, 1988 were also cool. Buick will always have a dear spot for me. My Great Grandfather used to have a 1970 LeSabre with a 455. Orange with a tan top. He'd listen to Andres Segovia and talk to me about the stock market. I still have his 1992 LeSabre, and his red C1500 pickup (I LS swapped it).
Later big Buick engines had a cylinder core shift problem. When you have the pan off look for it. Usually number 2 will be shifted back. It can make it too thin to over bore. I avoid 73 and later if I can. This is a 75 or 76.
I’ve been hunting a 1970 455 big block Buick to drop into my 1985 Buick Regal limited sedan. Got a 350 vortec in it now from a 1997 Tahoe and she burns tires good now but that 455 with 510 pound feet of torque would seriously shred tires 😂
Can't wait to hear it run. Still hoping for a 94-96 LT1 test. I need to know what low buck power upgrades I can do to my 96 Buick Roadmaster sedan. Also a 350 Olds if you can dig up one of those. Thanks for the infotainment!
Good stuff Richard. Had my hopes up for a test run today but that scrubby thing needs more work. Is the intake cracked underneath the the carb linkage?? Thanks Richard!!!
I would definitely use the redesigned timing cover - oil pump setup from TA performance. The stock buick oil pumps are known to fail without warning, causing catastrophic failure. I've seen a few of these failures over the years, including the engines locking up, and a couple of engines grenading .
I used to run a 455 buick 60 over mild cam. Ran low 12's in a 78 cutlass 400 turbo 2000 stall 373 gears headers intake 830 holley. 3,440 lb without driver. Im 180.
Sean Murphy makes some top notch Carb’s indeed. I’ve used one of his Rochester Quadrajets before and honestly for the performance I got for a $500 unit there’s no beating the value. Summit charges a few hundred bucks more for an off the shelf Demon than I paid for a custom setup 4BBL Rochester Quad from SMI.
My favorite youtube channel. I would like to see some solid roller camshaft comparisons on a SBC 383. I am trying to decide on how big I can go and still keep peak HP around 6200 rpm.
nothing like some Hanta virus to go with your 455... cant wait to see a 455 on the dyno. I heard the 455 Stage I in a Buick Grand Sport Stage 1would beat a LS6 Chevelle.
I bet it would lol it would be driver whichever one slips up that tenth of a second but considering how much bigger a big block Chevy is compared to the other 3 olds Pontiac and Buick motors they made damn near the same power and torque numbers which be you would think. Shouldn't be right so if they are physically smaller then they are lighter so again an advantage myself I was pontiac the mid 70s had the 301 come out in Firebirds so out came that and in went either a 455 or 400 plug and play easy peasy and then it was a firebird the 301 was well their answer to the 305 Chevy v8 torque but trying to squeeze every bit of gas mileage out like olds 260 or even Chevy's 262 find a Monza that was a v8 and bam you got a recipe for a hot rod w a bad ass 350 it's tight but no worse than an s10 v8 swap I never worked on one w headers but it didn't need them either a good strong 350 or 400 in. A Monza was yeah a blast we made one from two once it was an olds starfire a Monza basically and the v8 parts from the Monza went in it with a built 350 just a small cammed iron headed one is all it needed lol fun car if you can keep from breaking it trust me
Sorry I'm late💪🏾💪🏾💪🏾... Buick power to the front Baby.. ta performance is about 30 mins away from my house and the Buick God's🙏🏽 all the info you need... But I can't wait to see how much they really can take HP wise🧐🧐🧐..
Gotta say I would chuckle if a rod was broken in half and the oil pressure still looked really good. Hopefully it's not the case and it's just a bent pan. My prediction is 325hp without the 70s full exhaust, super lean carb and improved timing even if it is low compression.
Clearance is really tight between the rods and the oil pan. I had to pull mine back out of my car to beat the dent out of the pan. Thats a post 71 intake. Its loaded with all of the EGR garbage
Mr Holdener, how about a 70's style 454 build? Some stock rectangle port heads, and run the ls6, l88, zl1, and other factory solid flat tappet cams? Junk 454 at 7000rpm plus, just has to be a great idea😁
I love the ls stuff because of the great cylinder heads. I do think it would be great to show young folks how we did the same kinda things way back when with big block chevys. Any old 454, factory rectangle port heads, and some 260-280@50 solid flat tappet cams. We turned them 7200 rpm plus, made some beautiful noise, and broke lots of stuff. It was great😁
My buddy had a 70 stage 1 that he had no idea what it was . Car was hit on every panel but he would smoke every car taking off from a light . His uncle gave him the car . I kinda knew what it was a few months after he had it . He wrapped it around a pole and came close to flatlining. I wish I would of grabbed the car before it went to junkyard .
Since you like going to the junkyard and work with donated engines, maybe an option, buy an oil can filter opener to cut the filter to inspect the paper element before you proceed with the rest, I know that they suppose to be engines that were running but still it will safe you a lot of time and give you an idea what is happening with the soft metals inside the engine. a that moment you collected that engine.
That 455 may have been remanufactured/rebuilt at one time. At the 3:05 mark you can see what looks like the little over heat tell tale discs that reman shops put on the cylinder heads to see if the engine has been overheated.
i laughed when i heard that knocking sound. my dad had a 455 buick that was borrowed by a friend, and he set it down on a piece of wood, and it did the same thing. thought the rods were knocking until my dad explained it.
It’s amazing how nobody knows how rebuild, modify, jet, idle air tube tuning, THE AMAZING QUADRAJET .once done right it’s amazing! Low 10s high9s and still 25 mph city !✊
I have pair of heads on BB Chrysler that each head looks like it could have it's own thermostat housing/ temp gauge. Would they be good candidate to show difference of head temp i.e. 160F vs 245F showing hp & torque difference without changing block temp? Seems I recall head temp vs block temp affect performance and the dyno guy was wanting to change head temps without changing block temp for differences. These might be Marine engine heads.
Hello sir, a few weeks ago i asked if your videos colour choices for the run-by-run overlays on your builds in your videos was "colourblind friendly". You answered you didnt understand which is fine. Would you consider using or having a script programmer for the program add an allowance for each individual runs to be shown in example: run1 being ... then run2 using .-. Then run3 using .-- etc. It would honestly help a few other people understand the results more thoroughly, ya know appeal to even more of an audience i dont know just a thought. Love the content sir wish ya all the best with the channel🖒
@@richardholdener1727 yes sir thats basically it. Sorry if i was not clear or gave too much explanation. Again its just food for thought, love the content🖒
Richard, I'm guessing that the engine is a '75 -'76 based on the HEI. These engines were rated at 205HP (net) I think, so I'm really curious what it does on the dyno. I'm even more curious to see how much power some intake/cam/head/exhaust modifications add to the engine. I absolutely love this channel- keep doing what you're doing!
@8:07 is that a nasty crack on the exhaust crossover passage of the intake manifold? Looks like an “opportunity” to see how nitrous would affect that🤣👍
Prepare yourself for torque. Seen plenty of those parade float Electra 225's run 12s with little mods back in the 70s and 80s. Curious to how far you can a buick 455 today.
What are the differences btw the old GM big blocks [Chevy, Buick, Oldsmobile, Cadillac, etc?] They all seem to be right around 455 ci; did they use the same castings & just machine them to difference specs [bore x stroke; obviously, cranks would vary] or were they entirely unrelated beasts? Curious, but not a car guy, so no clue about the history...
well, it saved my brothers truck from utter destruction, so it wins for me. drove a whole mile with NO OIL. the drain plug come out and drained all the oil. the stp stuck to the moving parts and saved it. put new oil in, fired it up, and the lifters only clacked for about a second. never had any problems. i use it to break cams in, along with a decent amount of zddp oil, and ive never had a cam failure. i dont even rev them to 2000rpm.(buncha bullshit)
@@dj13yrs1 When it says chrome vandium on it? that is some harbor freight stuff for sure. But back in the day 70's chrome vandium on wrenches kinda meant cheap. I have some of my dads old wrenches I'll keep forever that are chrome vandium. Just a soft spot for me lol!
You can use a map gas torch to heat up the aluminum slightly around the outside edge and then use a rubber hammer to tap it off it'll break the seal free
Awesome! I love Buicks. Hey Richard, did you think about pulling the intake to see if the rats stored any food in the heads? I hope you don't have any surprises laying on top of the pistons!
That's some of the reasons I shyd away from Buicks over the years the water pump electrolysis the oil pumps are a major issue w them often don't get me wrong they have gobs of torque if Pontiac and olds made a timing chain and water pump setup like Chevy that would have been the best lol but if I remember right the Buicks oil pump setup was sketchy at best and at 4500 rpms is when it would fail and in seconds you've got junk .. anyone remember what it was about ?
Looking forward to this one and the 429, and the 500, and the 292. Hell I look forward to all your videos. That was some pretty sweet rodent turd action on the top of that 455., probably give you an extra 5hp maybe even 10hp if it was squirrel.
Very surprised to see you using an API SP oil. Also if the pan to rod clearance is that shallow. wouldn't cranks-oil slap be a real problem? just in normal operation?
big, bad, buick. i had a 71 455, and i had the same deal with the oil pan,. lol. i removed pan, hammered it out and was good to go. it was a strong motor for low compression.
I can't WAIT to see him work his MAGIC on this beast😎 🤞
My first running car was a 70 Skylark w the 455 Stage 1 bored 40 over (462) a cam and a very large rejetted quadrajet

The first burnout twisted the driveshaft in half👍
2 words: TA Performance.They even make a 4bolt main aluminum 455 block.
been talkin to them a lot
Yeh. That block is ONLY $6000. You know, Pocket change! 🤣🤣
Love the BOP 455s!
We gotta get this thing up and running again asap!
510 ft lbs and the sound it makes through dual exhaust with x crossover puts a chill down my spine

Summit charges a few hundred bucks more for an off the shelf Demon than I paid for a custom setup 4BBL Rochester Quad from SMI.
My favorite youtube channel. I would like to see some solid roller camshaft comparisons on a SBC 383. I am trying to decide on how big I can go and still keep peak HP around 6200 rpm.
why run solid for only 6200
nothing like some Hanta virus to go with your 455... cant wait to see a 455 on the dyno. I heard the 455 Stage I in a Buick Grand Sport Stage 1would beat a LS6 Chevelle.
I bet it would lol it would be driver whichever one slips up that tenth of a second but considering how much bigger a big block Chevy is compared to the other 3 olds Pontiac and Buick motors they made damn near the same power and torque numbers which be you would think. Shouldn't be right so if they are physically smaller then they are lighter so again an advantage myself I was pontiac the mid 70s had the 301 come out in Firebirds so out came that and in went either a 455 or 400 plug and play easy peasy and then it was a firebird the 301 was well their answer to the 305 Chevy v8 torque but trying to squeeze every bit of gas mileage out like olds 260 or even Chevy's 262 find a Monza that was a v8 and bam you got a recipe for a hot rod w a bad ass 350 it's tight but no worse than an s10 v8 swap I never worked on one w headers but it didn't need them either a good strong 350 or 400 in. A Monza was yeah a blast we made one from two once it was an olds starfire a Monza basically and the v8 parts from the Monza went in it with a built 350 just a small cammed iron headed one is all it needed lol fun car if you can keep from breaking it trust me
Yes it would. There is a reason they call the Buick Stage 1 "Hemi Killer"
I've been waiting for this
Sorry I'm late💪🏾💪🏾💪🏾... Buick power to the front Baby.. ta performance is about 30 mins away from my house and the Buick God's🙏🏽 all the info you need... But I can't wait to see how much they really can take HP wise🧐🧐🧐..
It’s a rebuilt engine, I saw the overheating stick on tab in the freeze out plug. Rebuilders use it for warranty purposes
Gotta say I would chuckle if a rod was broken in half and the oil pressure still looked really good. Hopefully it's not the case and it's just a bent pan.
My prediction is 325hp without the 70s full exhaust, super lean carb and improved timing even if it is low compression.
The angle grinder will make those exhaust manifolds bolt up reversed 👍
Grind the block or manifolds?
Clearance is really tight between the rods and the oil pan. I had to pull mine back out of my car to beat the dent out of the pan. Thats a post 71 intake. Its loaded with all of the EGR garbage
Mr Holdener, how about a 70's style 454 build? Some stock rectangle port heads, and run the ls6, l88, zl1, and other factory solid flat tappet cams? Junk 454 at 7000rpm plus, just has to be a great idea😁
I love the ls stuff because of the great cylinder heads. I do think it would be great to show young folks how we did the same kinda things way back when with big block chevys. Any old 454, factory rectangle port heads, and some 260-280@50 solid flat tappet cams. We turned them 7200 rpm plus, made some beautiful noise, and broke lots of stuff. It was great😁
My buddy had a 70 stage 1 that he had no idea what it was . Car was hit on every panel but he would smoke every car taking off from a light . His uncle gave him the car . I kinda knew what it was a few months after he had it . He wrapped it around a pole and came close to flatlining. I wish I would of grabbed the car before it went to junkyard .
I love Buicks, grew up on them.. but i blew up A TON of them too lol
Am I seeing a crack in the intake manifold under the carb linkage?
All of the typical old junkyard engine problems. Literally all in one video!
Is that intake not cracked near the linkage? 8:38
Looked like it to me as well
@@bicylindrico glad someone else thinks the same...not sure what else it could be...
Since you like going to the junkyard and work with donated engines, maybe an option, buy an oil can filter opener to cut the filter to inspect the paper element before you proceed with the rest, I know that they suppose to be engines that were running but still it will safe you a lot of time and give you an idea what is happening with the soft metals inside the engine. a that moment you collected that engine.
WE HAVE A FILTER CUTTER
Really enjoyed this video, thank you for doing this.
Is that a crack in the intake?
Good luck sir!
Is it me or do you have a cracked intake manifold on the middle cylinder runners on the right side ( front side view ) or is it a casting line ?
That 455 may have been remanufactured/rebuilt at one time. At the 3:05 mark you can see what looks like the little over heat tell tale discs that reman shops put on the cylinder heads to see if the engine has been overheated.
yep-at least the heads have been gone through-we know that much
I hope it isn't hurt too bad!
i laughed when i heard that knocking sound. my dad had a 455 buick that was borrowed by a friend, and he set it down on a piece of wood, and it did the same thing. thought the rods were knocking until my dad explained it.
Great video, it was fun to watch.
Is that a big ol' crack in the intake manifold heat crossover (?) ?
Is that a rod knock? Yep it's knocking on the oil pan. That's hilarious.
Have you done a intercooler pipe size test? 2 inch vs 2.5 vs 3.0. I didn’t see one when I searched. Would be cool to see
I can't find the article , where they compared all the big block muscle car era engines and iirc the buick came out on top even beating the hemi
What happens if you flip the exhaust manifold upside down and side to side?
Is the intake cracked?
It’s amazing how nobody knows how rebuild, modify, jet, idle air tube tuning, THE AMAZING QUADRAJET .once done right it’s amazing! Low 10s high9s and still 25 mph city !✊
I like the buick 3.8 v6 personally...🏁
I have pair of heads on BB Chrysler that each head looks like it could have it's own thermostat housing/ temp gauge. Would they be good candidate to show difference of head temp i.e.
160F vs 245F showing hp & torque difference without changing block temp?
Seems I recall head temp vs block temp affect performance and the dyno guy was wanting to change head temps without changing block temp for differences.
These might be Marine engine heads.
Or industrial/motorhome 413 heads.
@@karlsracing8422
Chrysler fan, you must be?
Curiosity of this has me wondering for years.
industrial 413 heads. came in big trucks and motorhomes. horrible for performance, but great for your idea.
@@frigglebiscuit7484
Mine, on motor that was free.
No other attachments,
Best kind!
Hello sir, a few weeks ago i asked if your videos colour choices for the run-by-run overlays on your builds in your videos was "colourblind friendly". You answered you didnt understand which is fine. Would you consider using or having a script programmer for the program add an allowance for each individual runs to be shown in example: run1 being ... then run2 using .-. Then run3 using .-- etc. It would honestly help a few other people understand the results more thoroughly, ya know appeal to even more of an audience i dont know just a thought. Love the content sir wish ya all the best with the channel🖒
I DON'T KNOW WHAT YOU MEAN BY SCRIPT PROGRAMMER AND STILL DON'T UNDERSTAND WHAT YOU NEED. ARE YOU TRYING TO DIFFERENTIATE THE TWO LINES
@@richardholdener1727 yes sir thats basically it. Sorry if i was not clear or gave too much explanation. Again its just food for thought, love the content🖒
Richard, I'm guessing that the engine is a '75 -'76 based on the HEI. These engines were rated at 205HP (net) I think, so I'm really curious what it does on the dyno. I'm even more curious to see how much power some intake/cam/head/exhaust modifications add to the engine. I absolutely love this channel- keep doing what you're doing!
EGR and HEI. That engine is at least 1974 to 1976. Any chance there’s the typical casting date on it?
@8:07 is that a nasty crack on the exhaust crossover passage of the intake manifold? Looks like an “opportunity” to see how nitrous would affect that🤣👍
NO CRACK-NITROUS WORKED FINE!
Prepare yourself for torque. Seen plenty of those parade float Electra 225's run 12s with little mods back in the 70s and 80s. Curious to how far you can a buick 455 today.
I've pulled plenty of cars out of the woods. I can smell that engine through my screen.
Finally! Something other than ford sb and Ls engines.
waiting with anticipation.
Love the qjet 🥰
What are the differences btw the old GM big blocks [Chevy, Buick, Oldsmobile, Cadillac, etc?] They all seem to be right around 455 ci; did they use the same castings & just machine them to difference specs [bore x stroke; obviously, cranks would vary] or were they entirely unrelated beasts? Curious, but not a car guy, so no clue about the history...
The one dislike is from Green Peace.
Project Farm did a test on STP oil treatment.
"F" for Fail.
He has a good channel
@Jeff Kopis thats bs. i use it and its never done that.
well, it saved my brothers truck from utter destruction, so it wins for me. drove a whole mile with NO OIL. the drain plug come out and drained all the oil. the stp stuck to the moving parts and saved it. put new oil in, fired it up, and the lifters only clacked for about a second. never had any problems. i use it to break cams in, along with a decent amount of zddp oil, and ive never had a cam failure. i dont even rev them to 2000rpm.(buncha bullshit)
It looks like it was STP branded oil, not the treatment.
@3:50 what eye protection? lol
Is the head cracked?
Nice video. Watched the whole thing.
WTH kinda chrome vandium wrench put the oil pressure gauge in??
Looks like a craftsman but i could be wrong.
@@dj13yrs1 When it says chrome vandium on it? that is some harbor freight stuff for sure. But back in the day 70's chrome vandium on wrenches kinda meant cheap. I have some of my dads old wrenches I'll keep forever that are chrome vandium. Just a soft spot for me lol!
crafts or pits
@@richardholdener1727 gedore!
I'd love a 455 for my car!
Can the manifolds be put on facing forward if they’re upside down?
That's some dirty oil. Looks like it coming out of an old school diesel.
Is the intake cracked? It looks like a crack in one of the runners.
You beat me to it. I hope it's a spider web or something.
Word has it out of all three BPO the 455 Buick was as light as a Chevy 350
You can use a map gas torch to heat up the aluminum slightly around the outside edge and then use a rubber hammer to tap it off it'll break the seal free
Just be careful around the block and don't add too much heat
Awesome! I love Buicks. Hey Richard, did you think about pulling the intake to see if the rats stored any food in the heads? I hope you don't have any surprises laying on top of the pistons!
It came from Frieburger (if spelling is wrong I apologize to David) it will only last a couple of hours
All them mouse presents probably preserved the factory painted manifold
yes i cant wait.
Hate to break it to ya but your intake is cracked right under the throttle linkage.
That's some of the reasons I shyd away from Buicks over the years the water pump electrolysis the oil pumps are a major issue w them often don't get me wrong they have gobs of torque if Pontiac and olds made a timing chain and water pump setup like Chevy that would have been the best lol but if I remember right the Buicks oil pump setup was sketchy at best and at 4500 rpms is when it would fail and in seconds you've got junk .. anyone remember what it was about ?
i believe those are stage 1 valve covers..
best part of the motor
Looking forward to this one and the 429, and the 500, and the 292. Hell I look forward to all your videos. That was some pretty sweet rodent turd action on the top of that 455., probably give you an extra 5hp maybe even 10hp if it was squirrel.
I think it was a head gasket. The way the water leak went under pressure.
Very surprised to see you using an API SP oil.
Also if the pan to rod clearance is that shallow. wouldn't cranks-oil slap be a real problem? just in normal operation?
it should not be that tight
Can’t wait 😊
big, bad, buick. i had a 71 455, and i had the same deal with the oil pan,. lol. i removed pan, hammered it out and was good to go. it was a strong motor for low compression.
It's been a while. When is Happy hour and horsepower back on??
MIGHT DO THOSE LIVE!
Great stuff
