[Dark_5.0]

Every track I have ever been to 5.0's and LS1's are king.

You are obviously dealing with some much better air than I am cause the best trap speed stock I have seen is 97 mph out of a 99+ GT.

There is a 99 cobra that runs good out here but he is the only one. He runs a 12.40 @107 on a untouched engine. With a solid axle with 4.10 gears , slicks and suspension. He pulls a 1.40 60ft.

My cobra runs 14.0's more times than not.

The air here is bad..
