Need some advice.....Im new to the SBC engine build scene. Ive got a SBC 400 bored 0.040. Planning on alluminum 64cc heads, 200cc runner, roller cam/lifters ect... trying to build somewhat of a "mildly hot" street motor with fairly aggressive (nice sounding) cam. Plan to not race it other than from street light to street light behind it will be a 700r4 for the occasional long weekend run
I think I may have went wrong on my piston choice...Ive got 15cc dished. Got the block back from being cleaned, new cam bearings, crank polished, freeze plugs, pistons put together ect. So I decided to see how far down in the hole the pistons set (goal of CR 10:1 - 10.5-1). Pistons are .040 down in the hole at least. Combine that with an 0.41 head gasket it takes the CR down to 9.6:1. Also just recently learned about "quench" which with the dished piston doesnt work out. What would be my best approach at this point.....New flat top pistons? Deck the block .040, but then that would change geometry by a fair amount? What I can figure is that standard deck would leave stock piston about 0.020 - .025 down in the hole and some aftermarket pistons add to that by .020 sometimes, giving me my .040? Or am i thinking about this too much and I just need to run with it at 9.6:1 and .081 piston head clearance, will I be able to produce 400HP with at least 400 torque??? Looking for advice, or if im being an idiot would appreciate knowing that too! Will much appreciate any recommendations you guys may have!!
