I dyno'd my stang today. The hp was like OUCH....142hp at about 3400 rpm's the torque was good at 240 at 2800 rpm's For some reason though it just dropped quick after 3500 rpm's. I'm guessing the engine I got was rebuilt to 79 5.0 specs It had close numbers with that original engine. We are sure the problem is the stock exaust manifolds, the car cant breath and the cam is crappy. I was pretty disapointed. I was hoping for 200 hp. But atleast now I have a base and I have an idea of what I need to do first. I need headers!!! What can I get with a 5 speed tranny?
