Need dyno results of GT40 P's
 

Does anyone have them and if so what did or didnt't do and how well did they work? I have seen people on the net use them, but I havent found one dyno graph. Anyone?:confused:

Check out the September 2003 issue of Muscle Mustangs and Fast Fords, page 168. If you hurry, you may still be able to find it on the newstands. It is in the MM&FF's Ultimate Guide to 5.0 Cylinder heads, Part 2. It should be all that you need. They were worth 30HP and 17lb of torque on the test engine. BTW, Nice T-Bird!
