Dropping the denali off tomorrow for a completely built tranny with a 2500 stall, then it's going to get the engine completely rebuilt. The lq4 block is gonna be bored 30 over with forged flat top pistons, rings, ported and milled 317 stock heads, hardened rods, lifters, springs, rockers, and a well mannered custom grind comp cam. Anyone have any idea what I should expect as far as hp on this build? The person building it says about 430 to 450. Just want to know if there is anything lease I should have done while the engine is apart.
