My truck previously ran between a 14.5 and 14.7 with a best of 14.4 at usually 97mph and a best of 98mph. That was a stock head lq4 with a 212/218 and 3.42 gears. I swapped to a 3.73 gear tr224 and a set of lightly home ported 243's. I only was able to get one run in because our track was having computer issues. But right out of the box it ran a 13.7 at 100.7mph with a 2.17 60' . I wish I could have gotten another run in because I left out easy worried about spinning but it did not spin. I think it could have went a 10th or two faster. But overall Im pleased since the truck is a full weight ecsb towing package and all. With 20 inch factory rims and a stock converter and g80.
