Hell Im clueless, I had a 67 on a V6. Again, dyno #'s dont impress anyone that has a clue, show me some timeslips. I can guarantee you, no matter what tires you have on it, it will be a horrible street car. The boost will come on so fast, you wont be able to plant to the ground with the best suspension, again spinning tires was cool at 16-17. Did you ever think thats why they put that set-up in a 6,000 pound truck...to get that mass moving.
