I made 271rwhp and 303ftlb SAE corrected at Brothers Performance with the following major mods:
-GT40P's, stainless valves, .560" lift springs
-Cobra intake with home ported lower
-Crane 2031 cam
-Crane 1.7rr
-MAC LT's, Dr. Gas X, and Bassani Mufflers
-Plus all the normal bolt-ons.
These aren't the best numbers, but they do reflect a 20rwhp & 8rwtq increase with just a change from shorties, catted h, and slowmasters. Plus, my car needs to be re-dyno tuned badly, since it has a 2 year old tune, that was made with my old combo....
