I had a 383 stroker built for my chevelle with a 488 lift cam. I just completed a disc brake conversion and I am concerned about vacuum for the brakes. How much vacuum will a 488 lift cam produce at idle? hereare the specks on the cam.488/488 lift 232 intake 234 Exhaust 292/300 total duration . eagle rotating assembly 30 over flat top pistons.
