Gotta disagree with you. I trophied at OCIR in early 1970 with my '69 340 Swinger, 3.23 non SureGrip, no headers, running G/Pure Stock at 14.28 @ 98+ mph. Just a really good tune. Wish I still had the trophy - and the car.
So you didn't just go to the track and race you just had a really good tune.What did I say.Oh yea I had a 68 gts that ran 12.90s all day The only differance was a posi and 3.91 gears.
