Bryan, what are your engine specs now? I had a look at your website, but it still shows a cast head 351W with a Performer manifold and a 600 Holley. Somehow, I can't see that motor running 129+mph
Do you still have the manual trans in there?
129+mph ---- geez that's a good speed!!!
Do you have the time slip? If so, what were your 60ft, 660ft time/speed, 1000ft etc. I'm not doubting your time, I'm just interested to see how much mph you picked up in the last 660ft.
Congratulations on your results,
Craig
