60 over 454 with L2377 flat top pistons. is there a moderately priced aluminum head with small enough chambers to make 9.5 to 1 compression? what cam?
going in a 63 vette with 3.70 gears and a 4 speed.
You really dont want those Vortec heads - just not good from a performance standpoint. Best bet is the 100cc Eddy's or get a set of the closed-chambers and do them up. Either way, with flat-tops your not going to get alot of compression. But, for what your looking to do, it may not be a big deal anyway.
You could stroke it, that's worth some more compression...
Vince is correct. To get any compression out of your motor, these are your only options.
If it were me I'd look for a set of semi-closed chamber heads (casting # 215 or 063), install 2.19 / 1.88 valves, do some minor bowl porting, flat mill them down to around 100cc and use a steel shim head gasket. This will get you around 9.5-9.6 scr.
