Not to hijack, but how much more HP will the stage 1 thumper make over a set of stock GT40 heads? Over GT40Ps?

Good question.

HMMMM... some one would have to build and then run the GT40s, remove, then and run the P's , then remove, and install the ported heads.... Dont think anyone can do that unless you are high dollar shop with a dyno!! I'm not! Try this... the GT40s are good heads... the P's are better heads.. the "Ported " Heads are better than those...... If you are looking for hard numbers.. dont think there are any!! At least not thru me.. I do know of a person with an Automatic car ( pretty consistant at the track) gain of 10 HP over my Ported E7's with a set of 'Brocks ( went 1 tenth faster in the qtr) I also know the PORTED GT40s are faster than the ported E7s... ( bigger valves ) SOOOOOooo..... I guess some one whos has had E7s and went to 40s would have to say their experiance , cool??

Just me................................
