454/502 hybrid custom build...
hey guys,
i just recently picked up a 1997 Vortec 7400 series 454 shortblock that had 502 HO heads on it from the 502HO crate engine and to top it off a Arizona Speed and Marine Chevy TPI fuel injection setup thats basically the RAM JET.
Several questions...
I want to change the cam and the pistons in the shortblock considering its for a truck to bump up the power...
im looking into comp cams XR288HR and a set of forged pistons to bump up the compression...
the stock heads on that engine are 99cc chambers and make 9.1 CR...these 502 heads are 118cc chambers so what piston can i use to get around a 9.5-10.1CR???:confused:
Any helpful hints, ideas, .02, anything that can help....
Thanks guys...
JUSTIN
