I kept my 2.59s in the rear and the car would run a best of 12.90s@107-108 with 2.1 60's. Now, later when I sold the car to my buddy, we put some 3.73s in it. The the best trap speed LEAPED to 114.2 mph on a cold pass. He ended up running a 12.5@110 with a 1.86 60' hot lapping on a humid night.

At any rate my point is if you don't have some 3.73s or 4.10s that may be the last piece to the puzzle. If you do then...sorry I will shut up
