I have question hopefully someone can help with. My son recently changed cams in his 350 290 hp crate motor. It only has about 5000 miles on it. Would this cam be any better than my stock cam in my 87 MC SS 305. It has mild mods, ie: performer intake, Holley carb, headers dual exshaust and stock 3:73 rear. It is no longer computer controlled. Thanks.
