Davin, my good man: Oof, you Chevy boys.... :-) That thar 440 oils through the rocker shafts, not the pushrods. In fact, there is quite the different oiling system in that engine you might want to investigate because that's the biggest thing that can derail a 440 build - oiling. Critical stuff. Other than that, the forged crank, the block, all of it is pretty much freight train bulletproof. Have fun! -Ed on the Ridge
Wait....this guy didn't know the difference between the MOPAR and Chevy oiling systems, and he's on a YT video rebuilding this engine? Forget it I don't even wnt to finish the vid. I expect top-level guys when I see these kinds of vids, not people that make major mistakes.
@@davidschmidt6013 Awww come on now, Davin is the MAN. Dude has definite skills and he's rebuilt all sorts of vastly different machinery - yes, sometimes learning on the fly while doing so. That's ok though - we get to go along for the ride free of charge and learn along with him, which I think is a major part of the appeal here. Cheers, Ed
One of your best tear down videos. Earlier videos had the action sped up so much it was hard to take in the details of each part as the parts were removed. This one is Excellent!
I love watching you do the engine tear downs and rebuilding. I also Love that Buick straight 8. One last thing, the date codes on the side of the block for MOPARS are the date, time, and shift the block was cast. Assembly came later, and being from early 1972, that would probably make it a 1973 engine. Hey, Chrysler had produced lot of the forged cranks and when performance went out of fashion, they just used them up.
After the spanking they got in the comments for the way the new liners were fitted, it's gonna be a while, either because the owner will have demanded it be redone correctly, or because they've had to find a fresh block. If the latter, the spin will be "found other issues in testing" rather then "we screwed up".
@@damanifesto - I'm a Cinematographer by trade, from a family of Mechanics and Technicians (my Mother taught me to Drift,.. :D ) - I was taught how to do insert-liners properly, including machining out the carriers for the Disc's on my '66 A body Valiant, and making my own liners to fit in them, with the carriers heated and liners cooled, dropped straight in, never had any issue once seated, cooled, and rebored to match the bearing sizes.

January 1972 I was going to school at Denver Automotive and Diesel Collage. Oh I had fun there !!! I am now 67 and just got my first performance car. 2008 Bullitt Mustang # 1925. I have not turned on the radio since the day I bought it. Hoping to install a Edelbrock Stage 1 super charger on it soon. We will see. Thanks for this one !!!
Stock RB and B mopar oil through the rocker shaft through one passage per side through the block. Minor issue... but that bugged me too. Evidently hagerty needs to do more mopars!
@@Welcometofacsistube - never got those Down Under, we had Hemi-6's by then :) They're nicknamed 'rattle monsters' for the hydraulic lifters habit of leaking down just enough to hear. :D
Knew a guy with full body/glass 71 roadrunner, full iron 440 8-71 blower on methonal ran 9s at 5200ft. Granted he was A.S.E. cylinder head expert amd had wet flow bench but still amazing power. Plus after whole season bearings still had coating on them. Amazing engine builder
As well as the early Hemi he rebuilt, the Buick Nailhead, the Buick straight 8 and the Chevy 216. Surprised he didn’t catch that. Oops, mea culpa moment in the next video I bet.
Just from looking at the outside of the engine it looked like it had been worked on before. With the modified oil pan to what looked like maybe the old vacuum balance tubes on the valve covers ( something that was popular in the 70's & 80's ) to the mismatched heads. I think it is a case of different lots of valve springs mixed than some of them getting too hot because if they got hot enough to change color it would soften them up and change the spring pressure greatly as well and that's easy to check with a spring tester.
Whenever I hear Davin say we are going to "tear down" something , it is like listening to chalk screech on a chalk board. While working for Cadillac Division we were working in the engineering shop and I mentioned tearing down something, I was immediately chastised for doing so and informed that a true professional 'disassembles' and 'reassembles'.
Since I watch and comment on all of these wonderful videos I don't feel too guilty making a critical comment. The videography is taken to an art form, which is fantastic, but slow motion of someone scraping off a gasket or poking at sludge in an oil pan really doesn't serve any purpose and begins to irritate after awhile. Slow motion of a complicated activity is very helpful. I hope this comes across as constructive criticism. Thank you for all the effort that goes into making these videos.
Hi, I have written before and want to again point out the "Snowball's" coupe is a 1940 not a 1937. The hood is a '37 but the body is a '40. Note all 1937,1938, and 1939 except woodies have the wipers on the roof. This is because the windshield swings open. The "40 is fixed and doesn't open. On the race car there are no holes in the roof but it looks like patches on the cowl where the wipers would have been located. Thanks, George
NC state troopers ran the 440 for a while. I was at the world 600 when Richard Petty debuted the 440. After the race he said it was like driving with a barn door attached to the front of the car.
Exelente trabajo , felicitaciones también por el video tan bien logrado. No sabes las ganas que me dan , de ver cómo arreglarían en tu taller , el motor de mi carro. ! 😅 Los felicito a todos y seguiré viendo todos sus videos. Y espero algún dia conocerlos . Dios los bendiga
No mention of the dual row roller chain timing kit? That motor has been done as a tough street engine, bet those heads will show up as mild match-ported.
what does "mild match ported" mean? I know next to nothing about mopars, but was thinking that one of the mismatched heads might be a low compression/emissions head....
@@fleetwin1 Means instead of porting out to larger valves, all that's been done is to match the sizing between all the ports to flow identically, and to ensure there's no stepping up or down in size between the exit of the intake manifold and the port on the head. When added to a proper balancing (as Davin showed in the video), balanced and match ported makes the engine run with less vibration and no uneven loading on the internals, so will run stronger and longer. Even though those heads are different years castings, they're for the same base design, and matching the porting across both heads mean there will be no difference in power made side to side of the engine, assuming the chambers are the same number of cc's volume.
@@frigglebiscuit7484 Just mild work, not super wild. No point going too wild for the street, engine just gets nasty to live with, far easier to build mid range and do it right, then add a clutched blower or a turbo.
Hey Davin, I would really love to see you guys work on something a little differrent... The BMC B series 1800 engine is used throughout the world and has a great aftermarket parts community... I would love for you guys to strip one down, do a heap of performance mods and then get it all put back together... then there is the added benifit of having to build a car for it and THEN taking that car to some track days!! there are zero nbegatives to this idea! :)
I love Mopar "B" engines. Steel crank? Pistons skirts looked low mile. I wonder if the larger CC head has been shaved to make up the difference? 2.08 & 1.88 valves? I sure miss my 1963 Dodge 426 Stage 2.
This is art, you're doing, mister. I'm a sub', and looking you since Reunion Island (little French Island), and I can assure you, I always enjoy watching your videos, and that little moment at the end, when the engine is purring... it is perfect! I'll have to same same with my engine (EU engine, so, less impressive, but I want to do something that could be as respectful as you when you work on engines).
Davin: When the low compression low-lead / no-lead era was phased in, Mopar reduced comp ratios by moving the wrist pin loacation in the pistons. So your fraternal twin heads should not be a big issue, but if the pistons are original, your '72 vintage block will have a comp ratio slightly over 8 to 1. It won't get anywhere near 600 HP. Obviously the bottom end has been appart... more detective work needed!
My thoughts = $.02 is with 2 different heads one having the blue springs and the other only 1 blue and the rest purple that they had a broke or weak purple spring and replaced it with a later model blue one. Like I said 2 cents..... love what your doin!
The reason why oil goes up the pushrod tube is why would it ever go any other way? You’ve already got galleries around your lifters and camshaft, the pushrod should be hollow, anyways, and you get oil delivered to each rocker arm and valve in the minimum time after startup. Lubricating the rocker shafts means you either have to have tons of galleries going up the head.. or small points of failure where sludge can build up and not just take out one or two rocker arms and valves.. but a whole bank of them.
Always enjoy these videos only problem when you did the model A engine went to fast and took me about 4 attempts to work out how to remove valve springs.....one time when being young and the internet are your worst enemy (Talked to 3 old mechanics who all learnt on those types of engines and were full of great help but not when i said wanted to supercharge it haha)
Those heads won't come close to flowing 330 CFM stock or even ported and give 600 HP streetable. Talk to the guys at Hughes Engines, the LA engine experts (and Elephant and new Hemi and "B" and Magnum experts!). Ported W-5 heads with a streetable cam and pistons that will run unleaded swill (that means a crank, cross-bolted mains, rods, pistons head work, the whole enchilada) and a dual plane intake might tickle 525HP but BIG torque numbers...long headers and an X cross-over pipe, maybe over 600 pounds/ft, which on the street, makes HP meaningless. You can't do a half-a$$ed job and have an engine hold together. I payed for a 1983 Suzuki GS110ED motorcycle at the Friday Night "run what-ya-brung" drags at $500 a pass against lots of DNFer's who thought they had built fast cars, even trailer queens. They had built hand grenades...expensive ones at that. FYI, a torque-monster you can just drive off the line like Granny going to the the grocery store and kill 'em in the 60' time and all they'll ever see is your tail lights. Just don't bury your foot in it and light 'em up!
Well, Here's what I see. Aftermarket Felpro head gaskets. TRW forged pistons.Probably the six-pack replacement with the valve reliefs, L2295f. Internal balancing (Mallory) on the forged crank. Double roller timing gear set (probably an old TRW part number) Modified windage tray. They never came with all the small holes. Obviously modified oil pan. Someone spent a little bit of money on the bottom end many years ago(70's or 80's) only to top it off with mismatched heads. The 906 has a different runner than the later smog head and you'r off on the CC's by about 8 to 10 cc's unless the heads have been milled extensively. Expect the CC's to be 88cc to 90cc's between the two heads. Keep the block, maybe the crank if you're not stroking, and I don't know why you wouldn't. Everything else is outdated junk. Get a matching set of heads, Pro Gear timing set, and dependable rocker arms like Hughes etc. OK, That was fun.
Chevy shop was into that motor in the past as any Chrysler guy knows the Rods and caps are stamped on the break line of the rod and cap what number hole they're in.
I really love and enjoy whatching the process of restoring, you’re the reason why i would like to study any enginering related with cars and motors. Could you please tell me how did you learn? Or do you think is better to learn empirical? Thanks and regards from Mexico.
If I remember correctly, the purple valve springs and spring damper were a "Direct Connection" performance valve spring. There was also a purple camshaft that was a Direct Connection performance grind that was available, but I couldn't tell whether it had that cam from the video. The 72 block had the cast crankshaft stock, I couldn't tell whether your crank had a wide or narrow parting line on it. The forged cranks were considerably more desirable. Cast cranks had an external balance, with a weighted damper and flexplate/torque convertor, so maybe that was the reason for the internal balance. There was a considerable CC difference between 68-70ish heads and the later heads, you may want to make sure they are close in volume. The later heads were also considerably lower performance versions than the early heads - again, if memory serves. Mopar 440 RB motors also benefit greatly from oiling system improvements, like blending the cast passages in the block and in the oil pump.
As a mechanic of 20 years. You could not pay me enough to use hand tools to take off anything I can use a cordless impact on. Any mechanic in their 40s feels hand pain or some other pain weekly lol
Hi, as I remember it the 440/383 cylinder head casting numbers were 906 unleaded and 456 leaded, otherwise much the same. Drag racers like the 456 because it is less likely to burn a valve. Or maybe my memory is faulty.
I love these videos. Davin, you do an outstanding job explaining & showing. But . . . Davin's producer, perhaps you could get Slow Mo Guys to come film gasket scraping at a million FPS (I never could understand why anybody wants to watch a wrench turn in slow motion).
This is a great series. Looking forward to see the progress of this rebuild. Looks like you'll have to shave the head with the bigger chamber volume to match the smaller one?
i like this guy cause actually gets all greasy and crap unlike those other shows like trucks they don't get greasy so why even work on an engine if your not getting greasy.
Thats s first for me on doubling the flow numbers is somewhere the horse power, I do wish you would let us see the pistions, cast or forged, I do hope you install the bigger valves, 1.88s and the 2.14s the 3 bolt cam is after market, would like to of seen the numbers, or have the lifts measured.
What pistons and rods are those that needed mallory metal added to the crank? Ballencer is for a steel crank. What numbers were the heads?? Unless you are getting a super deal from your machine shop, it is normally smarter money to buy aluminum heads. I hope you will give us a complete run down of parts in the next video....
This is literally my favorite thing to watch on RUclips. Always looking forward to the next one, keep it up
Without a doubt.

FYI, a torque-monster you can just drive off the line like Granny going to the the grocery store and kill 'em in the 60' time and all they'll ever see is your tail lights. Just don't bury your foot in it and light 'em up!
Torque wins races
ive heard very bad things about hughes engines.
Really good video , i'm waiting video to repair of the buick fireball 8.
Well, Here's what I see. Aftermarket Felpro head gaskets. TRW forged pistons.Probably the six-pack replacement with the valve reliefs, L2295f. Internal balancing (Mallory) on the forged crank. Double roller timing gear set (probably an old TRW part number) Modified windage tray. They never came with all the small holes. Obviously modified oil pan. Someone spent a little bit of money on the bottom end many years ago(70's or 80's) only to top it off with mismatched heads. The 906 has a different runner than the later smog head and you'r off on the CC's by about 8 to 10 cc's unless the heads have been milled extensively. Expect the CC's to be 88cc to 90cc's between the two heads. Keep the block, maybe the crank if you're not stroking, and I don't know why you wouldn't. Everything else is outdated junk. Get a matching set of heads, Pro Gear timing set, and dependable rocker arms like Hughes etc. OK, That was fun.
3:35 Unless it’s a magnum motor, Chrysler engine valve trains are not oiled through the pushrods.
Chevy shop was into that motor in the past as any Chrysler guy knows the Rods and caps are stamped on the break line of the rod and cap what number hole they're in.
I really love and enjoy whatching the process of restoring, you’re the reason why i would like to study any enginering related with cars and motors.
Could you please tell me how did you learn? Or do you think is better to learn empirical?
Thanks and regards from Mexico.
That thing is clean on the topend inside regular oil changes
If I remember correctly, the purple valve springs and spring damper were a "Direct Connection" performance valve spring. There was also a purple camshaft that was a Direct Connection performance grind that was available, but I couldn't tell whether it had that cam from the video. The 72 block had the cast crankshaft stock, I couldn't tell whether your crank had a wide or narrow parting line on it. The forged cranks were considerably more desirable. Cast cranks had an external balance, with a weighted damper and flexplate/torque convertor, so maybe that was the reason for the internal balance. There was a considerable CC difference between 68-70ish heads and the later heads, you may want to make sure they are close in volume. The later heads were also considerably lower performance versions than the early heads - again, if memory serves. Mopar 440 RB motors also benefit greatly from oiling system improvements, like blending the cast passages in the block and in the oil pump.
"Will go really well on this 1971 block based on the date code".... as the camera pans across the 72 casting date....
Defiantly not a stock, or after market oil pan... o_0 Someone had a lovely time welding that modern art form together... >_
As a mechanic of 20 years. You could not pay me enough to use hand tools to take off anything I can use a cordless impact on. Any mechanic in their 40s feels hand pain or some other pain weekly lol
That oil pan mod was so typical of the era that the motor was built. I see a Milodon oil pan in the future, for this build.
Hi, as I remember it the 440/383 cylinder head casting numbers were 906 unleaded and 456 leaded, otherwise much the same. Drag racers like the 456 because it is less likely to burn a valve. Or maybe my memory is faulty.
I love these videos. Davin, you do an outstanding job explaining & showing. But . . . Davin's producer, perhaps you could get Slow Mo Guys to come film gasket scraping at a million FPS (I never could understand why anybody wants to watch a wrench turn in slow motion).
Muy buen video y buen laburo los felicito saludo desde Córdoba Argentina sería bueno que algun video sea en castellano gracias 😎🖒
This is a great series. Looking forward to see the progress of this rebuild. Looks like you'll have to shave the head with the bigger chamber volume to match the smaller one?
I have tore down many engines. But I noticed when he tears down an engine music I don't ever recall hearing music tearing down in the engine.
Then you're not drinking enough. Turn up the radio!
YESSS A CHRYSLERR
i like this guy cause actually gets all greasy and crap unlike those other shows like trucks they don't get greasy so why even work on an engine if your not getting greasy.
Thats s first for me on doubling the flow numbers is somewhere the horse power, I do wish you would let us see the pistions, cast or forged, I do hope you install the bigger valves, 1.88s and the 2.14s the 3 bolt cam is after market, would like to of seen the numbers, or have the lifts measured.
My fav engine -
I like this guy. Knows his stuff without being Buba better than you.
What pistons and rods are those that needed mallory metal added to the crank? Ballencer is for a steel crank. What numbers were the heads?? Unless you are getting a super deal from your machine shop, it is normally smarter money to buy aluminum heads. I hope you will give us a complete run down of parts in the next video....
