    I run it in my '88 with a 165* stat with a 300hp crate motor. You will notice a drastic change. Especially in the pocket book when you discover it only works with 91+ octane. All kidding aside it is a fantastic upgrade. Add a MSD coil, gap your plugs at 50 thou and throw in a K+N and dual exhaust and hang on!!!1

    I have one on mine, but it was there when I got it. Judging from the temp gauge, its probably got a 160 in there, and I run 87 oct w/o problems
