That 35-40 hp, was taken using a stock fox mustang, with an Edelbrock Performer, and a 70mm tb.
FF&MM april 2004 issue said they got 40 hp out of the combination on a dyno, while the Brother's catolog claims it's around 35-40. Best bet on what you get would probably be 35.
When i switched to an Edelbrock Perfomer with my stock heads and cam i got 3.4mph out of it. Most say a mph is about 10hp. I went 97mph to 100mph. With that one mod. Id say Intake manifold for sure.
