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.
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?
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.
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.
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 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
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.
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!

Sounds like a hoot and a half!
@@EngineKrahnicles I'm looking to run mid 9s in the 1/4 with it NA in a G-body. It'll also take a 300-400hp shot of nitrous too just in case.
Slap a set of Brodix Dragonslayer 320 heads on that bad boy!
One of the reasons for the Tall Deck or Truck! On the original hi-perf block had notches for valve clearance cut into the piston deck
in the back of my mind, i knew that. thanks for reminding me!

Because the price was right and they are easy to find in big trucks. This block already had racecar stuff done to it, so it was a good candidate.
A Big block tall deck 490 cubic inch with a lil tiny baby ass camshaft .
It's for a rock crawler, so the torque is going to be more beneficial than peak HP

366 was the small bore version of the TD 427. Pretty tough old engines.
They look identical on the outside.
The reason for the tall deck blocks is GM used a 4 ring piston on the trucks.
I agree with drifter, I use a .025" hole.

Terrible milage, all the torque, heavy, no HP, bulletproof. Sounds like a good matchup

The block already had them on there
I would take those plugs out in the front and either Terrill a new set with a smaller hole like .020 .030 you said you did a 1/16 hole that’s to large
I've never had a problem with oil pressure. Done that on dozens on 350's and always have 40lbs

Dude, no one needs your sas. They were parts laying around, so you may as well use them. Go get a bud light on me, because you seem like the type
@@EngineKrahnicles Sas...? You're getting offended over that? Lighten up and keep the beer it's definitely your type...
