SBC 406 with comp cams XE284h 

skrilx12345 correct. Block was decked due to previous overheating. Flat top pistons with no valve reliefs also bump compression up. 72cc heads were a must in order to keep it on pump gas.

C10video 1 ahhhh I seeeee

Local exhaust shop just couldn’t bend 3”. My plan was to order some bends and finish it out in 3”.

Francisco Huerta 383 forged eagle crank, forged scar rods and forged wiseco pistons, with a set of World Product heads. It’s about 10:1 compression, built for a little nitrous, and I’m running the same camshaft I had in the 406

Francisco Huerta I had my world product heads on it. The heads were not drilled for steam holes and I used a block off head gasket to try to get around it. Unfortunately the block cracked clean down the steam holes and when it did it destroyed the bottom end. I learned my lesson on the 400 for sure. Gonna stick with the 350 block where I don’t have to worry about steam holes and parts are much more available

Not a clue. It was Healthy, but not gonna set the world on fire.

Francisco Huerta thanks man! Unfortunately it’s been sitting since shortly after this video was taken. Building an engine for it now, should be ready in the next few weeks. Paints a little rougher than it used to be but stay tuned for new content on it coming soon!

CASANOVA 87' BoxChevy Not a clue. This engine cracked the block between the steam holes before it ever even made a pass

Tim Kennedy Thrush welded mufflers, they are pretty much just an offbrand 40

C10video 1 nice. I had thrush on my jeep. My car was done a long time ago with Flowmaster Top 10 Shootouts. They weren't out very long or too popular because their size. It's pretty much a Delta 40 in a 70 series case.

I'm not exactly sure, I don't have access to a dyno. But I did some readings on a similar build with hotrod magazine and theirs made around 470 with a more aggressive roller cam. So my best guess would be the 400hp range

Yeah I'm debating switching to a roller cam next winter

Spend the extra money and do it. You will regret it if you don't. I know I do.
