okay, so i work with this dude that is all about turbo dodges. like the shelby csx and the omni and shit. they all use cams from the n/a versions of thier motors and get a good 15-20 hp out of them. would this rule also apply to the 7m? i have a 90t and there is a 89 n/a in the yard i could get the cams for like 30 bucks. anything worth it?
