I guess I have it all figured out... my cam has to be a B cam. Lope sounds similar to other B cam videos I saw on youtube, plus my car does open up at around 3500 RPM.
I'll throw mine in, stock 5.0 MAC shorties, Pypes O/R X pipe, Pypes violator mufflers, flowmaster tails YouTube - Mustang 5.0 pypes exhaust
YouTube - '91 Coupe exhaust clip There's mine, Custom Bullet Cam, GT40Y heads, GT40 intake, 1 3/4" LTs(too big), X-Pipe, and Flowmasters.
