Question? I have a 90 with a L98 350. The top end was a little nosey So I replaced the lifters - pushrods - rockers ( with Crane golds - had the heads completely redone with new Z28 springs AND SVO injectors, RESULTS! this THING is still nosey! the cam looked good ( no flat lobes or minumal wear ) what's up with this???? I've been told that the roller L98 is a nosey motor but I'm not buying it! any help or input here would be a great help.

Jim,

Welcome to the Corvette Action Center.

When are you hearing most of the noise? At idle? Upon acceleration? Wide open throttle?
