The reason I'm asking is because I've been foot braking it at 2500 and it has run a best of 10.05@134 with a ****ty 1.44 60'. Wondering what to expect or work to get once I start leaving off the trans brake at around 4000. I have a 5500 stall converter. I think it should be going a 1.38 60'. It two weeks I have a track rental and I'll be able to try different launch rpms and shock settings. Should a 1.38 be hard to get?
