Andy prefers to test-install the cam before setting the crank in place. This way, if there’s any issues with the cam bearings it can be easily addressed. All new GM blocks come with the cam bearings pre-installed, so that’s one step we get to skip. We want our Camaro to have the same great street manners it had before, so we only bumped up one size in the COMP catalog. The old one was a 232/234 at 112, and the new one is a 238/240 with the same 112 LSA. With the extra 38 cubes, the change in idle characteristics should hardly be noticed.
