Finally 8.0’s

If you still have the 904 I would put it back in especially if it has the low gear set. 2.76 1st gear and less rotating mass puts more power to the tire. You could also borrow a set of 26" tires 235/60/15 or 275/50/15 drag radials and the car will pick up another 1/10 in the 1/4 mile.
