Us too, We have a 4-link Racetech with a 499. Last year it ran a 8.01 @ 164mph with 12.0 comp., Pocket ported SR's, .684 Comp roller, -2, 1050,and 4.10's. Over the Winter I installed max ported -1's, 3X, 1150, 1.6 rockers and raised comp. to 13.0. I'm hoping for 7.80's @ 170. Will find out next weekend.
