I just called Wilson manifolds and it sounds like they would do a similar reshaping on mine. It won't be cheap if I have them work on it but I have spent more$$$$ for a shot at less power gain.

There's probably 25 or so HP in porting it TO YOUR APPLICATION. But again because it isn't a wet application I don't feel that is hard to do for ANYONE who knows what their doing. There may be something obvious in the plenum. Pipemax will give you ideal intake track length #'s. I believe the power you got off the dyno..where does that put you in your 3050lbs? I think you're not using all you have. Just trying to sae you some unnecessary money.
