Kiekhaefer made Nascar and Offshore race motors out of them in the late 1960's and early 70's. Had to make so many motors to qualify as Chevy "production" so they even had Winters (factory) make/cast dual plane aluminum intakes for 2 days only in 1969, to fit the tall block. Pretty much everything in the motor was off the shelf "Chevy" but the best they had. Heads from this motor. Pistons from that motor. They stroked the crank to 4.250 and used 6.405 Rods making it a 482ci. Punch it out 60 over and you have almost a 496ci (495. something). The block walls are so think it you can go a 100 over with no issue. Also good for keeping the cylinders true when the motor is run hard for long periods. As for weight, I don't think the blocks are 25lbs heaver then the 454. I had to rebuild my motor and build a clone of it for a 1969 race boat. Cataloged every (factory) part number down to the last gaskets and bearings (and then built a second identical motor). One thing I found wild is Crane (the cam company) did all the porting and polishing of the heads and intake. Something they haven't done in many years. My balancer had to use a 454 flywheel and drilled it instead of trying to add all that weight to a neutral balanced flywheel to make it work.
Dang, some of those commenting here either didn't watch the video or have poor comprehension. This engine is going in a rock crawler. It does not need aluminum heads or a big cam. The intent is to make tons of low RPM torque. That is all.
Building a 6.535 long rod tall deck .060 427 with a Bullet 276/282@.050 714/714 lift 106 lobe sep solid roller and a 335cc runner head, 12.6-1 compression. 1050 Dominator on a Bowtie singleplain intake. Good stout blocks to build on. Tractor pullers loved them back in the 70s & 80s. Mine gonna be around 439ci, but its gonna rev 8000rpm.
if its going in a fuel injected application with port fuel injection be sure of the cam firing order. or if its going in a carb application.. be sure that you do the check the air fuel ratio at 1700 and 3800.. 1700 to get the idle feed restrictions sized correctly and 3800 RPMs to get the primary main jets sized.
Chevy eliminated it for obvious machining purposes on their later Big engines. Also the nitrided steel crank for the 3.76 stroke… had a brand new L88 short block in 1987.
@4:55: These Tall Deck 366/427 low-revving and torquey truck engines were said to have 4-bolt main bearings and forged crank shafts. I'm not sure I saw any 4-bolt mains here in your video. And you didn't mention a forged crankshaft, either. What's the story about that here? EDIT FOLLOWS: Sorry! EDIT: OOOPS! @5:57 I caught sight of the rear main bearing, and it is clearly 4-bolt. And @5:59 the front 4-bolt main bearing comes into view. How many main bearings are there? Are those 3 strange-looking caps with the tower extensions on the inside bolts also main bearings? Gee, there's even an extension on the one of the front main bearing bolts. What is the purpose of these extensions?
489.17 cubic inches is what is to be precise. id rather say 490 also, but it always seems to be refered to as a 489 everywhere. anyway, i built an engine pretty similar to what you guys are doing. i used a 212° cam and peanut port heads, and 440 horse and 560 lb/ft. from what ive seen, the large oval ports are worth about 30 horse over the peanut ports in stock configuration. the 6° more duration you have is worth about 10 or 15 horses, i suppose. that should be a fun engine to cruise around in. why did he decide to go with a tall deck?
289...389...489! Sounds awesome to me! One major advantage with the tall block is being able to use longer rods. A longer rod to stroke ratio means less sideloading of the pistons and a longer lasting engine. Chevy did the opposite with the 400sb which caused piston cracking, loss of compression, and oil burning. It wasn't the siamesed cylinders that were the problem. It also wasn't the first engine with siamesed cylinders and certainly wasn't the last.
I got that engine completely stock it's a crate motor I just want to drive it in a car around I wonder how good it would be I'm going to put it in a 66 Chevy Impala
At about 3:39 he said 366? Did he mean 396? Cuz I've never heard of a GM 366 with the BBC canted valve heads so I'm kinda lost. Not a GM guy so don't hate but am I wrong thinking "what"? Plus does that even work with a "tall deck" block? Ok.
366T and 427T are real engines. They are in big trucks. So they aren't as well known. They both used the same heads. Good questions and thanks for asking.
I'm a little surprised you would spend the money on fire ringing the block and use oval port heads. Just a mediocre set of aluminum square ports would make a ton more power. Especially with the extra cubic inches. Not finding fault. Just curious.
541. But then you loose the beauty of that massively thick cylinder wall and get lots of engine weight. Your reliability goes way down, so to counteract that is really expensive
Seriously roller arms? Oh god if he says this engine is "Built" I'm gonna spit up my beer! I get it....yeah it's built! How can it run otherwise? Oh so assembled parts is just the engine not put together but all the parts are in the same area but with nothing labeling any part as high performance then.......? With or without those "built" parts it's still built in the same sequence to run right? Maybe could be. My shoes are just socks til I tie them I guess.....NOT! They're gravity protection so I don't fly away!
@@MrADVANCEDTEK dude, what are you smoking? Put down the bong. The guy has BUILT a solid stroker torque monster engine for his buddy with a rock crawler. The solution fits the goal. That your nonsense somewhere else.
@@msh6865 My What!! oh ok so this " The solution fits the goal That your nonsense somewhere else" is so supposed to make sense? Yeah? But no it's simple. If something is made then it's made again then what is the difference? Come on use your 3rd grade brain and tell me! Is it always made? Or is it always BUILT! Let's see what you call it because every engine is built but calling a engine BUILT is just stupid ass people that don't know the real meaning between doing and what is done! So go ahead let me see if you can prove me wrong! A engine not put together is WHAT? So a engine with the best parts put together is WHAT!!! SHUT THE FUCK UP!! You'll be talked to when you learn who you are allowed to talk to. Answer this...What engine runs without it being put together or built? I got a 1993 Ford feista 1.3l in pieces....so do you think you can "BUILT" it for me? Yeah but you thought you made so much sense....
