Just got an issue of "modified mustang"magazine and they tested a vista blue gt500 on the 1320.The car had less than 500 miles and 100% stock.They said with the f1's it suffered severe wheel hop. I'm not sure how many runs they took as it doesn't say,but the with a 1.90 60-foot it ran 12.41 with no mph indicated.Just wanted to pass it on with all the talk about stock numbers:beer:
