I heard you did good with the new headers. Can you feel the difference? I was over at Allans Yesterday to try and iron out some tunning issues but I am still waiting on the Greg Welds to come in.. :cry:

the car ran the same mph which is good considering the heat. allan says i gained about 12-15hp. how did you do with allan?

I picked up almost 17rwhp and over 10rwtrq with the ported fast and the nick williams tb. And that was through the new 4400rpm stall converter.

not a bad gain considering the 4400 stall.
