I know that Jack, but the article said these were factory cars with factory engines, why there was a 427 in a 69 Mach I, I don't know. The 427 had turned into the 428 CJ in 68, I heard there was a few of the 69 1/2 Mach I s' were given 429 CJs but have never seen one.
The 302 averaged just under 160 in the 3 mile indurance run, I would think that if they were factory set ups, like the article said, their top speed would be close to 165. Without ballast they would be close to airborne at that speed.
The brand new corvette run on top gear from the standing 1 mile just barely met the figures of the 302. So something just doesn't figure. I'm sure I will be enlightened by a Mustang guru, or Danny, which ever comes first. I raced a 70 shelby GT 500 back in 72 with my Torino, and his front end came off the ground at 145, scared the crap out of both of us.
