Corvette motor info ?
I just picked up a 91 Corvette motor and am looking for a little info on it. Does anybody have a link to a C4 web site or board with tech data on this motor? I am mainly interested in cam specs, HP, comp ratio, and whether they used flat top pistons or dished pistons with smaller combustion chambers to get the ratio. I read that these alum heads had 55 cc chambers, is there anybody on the board running these heads with flat tops in their Thirdgen?
