Great website! You really got alot of use out of your Vette.
That 14.1 at 104 would seem to indicate a loss of traction out of the hole. My old GTO ran a 14.6 at 107 until I put on some drag slicks., then a 12.88 at 110. (My stick shift days were a learning experiance.
My car does over 140 in 3rd gear at the track and is still pulling very hard with some gear left .... I had it up past 175 mph once in o/d with lots left. Not sure I want to go much faster.... but I want to be quicker
