So. I'm not into racing, nor do I have the finances to build a 500-600 hp motor, or the use for one. But I'd like a little pep in my Pony. I already have the basic bolt on's that most do right away. So I'm going with the Explorer intake, upper and lower. Also throwing in the TrickFlow Stage 1 cam, plus I got a set of hand me down GT40 heads. I haven't had the chance to put the 3.73's in yet either. Curiosity sake, should I be able to get an extra 10-15hp with this little upgrade?
