This is a 425hp motor. Fresh 2.02" stainless valve VORTEC heads. Big cam. Cloyes true roller chain. Balanced rotating assembly. Forged pistons. It will sound pretty wicked and yield 9.5 to 1 compression. Still fine for pump gas. This combo is very tough to beat for a simple hi horsepower - reliable, stable 6500 rpm screamer.
I can text you pics of the Vortec heads. I have standard sbc heads and air gaps intakes also if you need or prefer those.
