If I have a reaction time under 0.500s with a sportsman tree set at 0.500 in my category, I have a red light (disqualified) and I have lost!!!!
What is your rear-end set up to have a 60ft at 1.3s? What is your weight distribution?

It's the same deal with the lights....your perfect RT would be .500 Ours is .000 We still have the same .500 between lights and .400 on a pro tree. I still use the C4 Corvette IRS, but with the power I have, I've found it's limit, a couple times. I keep blowing half shafts out, usually on the line, but about a month ago at the big end. Going to put a solid rear in over the winter.

Bourret 60 ft 2.233 certainly doesn't surprise me. My 2.0 was the BEST ever for me! With the massive torque from a big block even a low rpm launch is extremely difficult to limit the wheel spin. You just have to take your time getting out the hole, or run slicks! :)

0.567 is not that bad on a 0.500 tree a pro three is 0.400 and not as easy to get the hang of. you need to work on your 60 foot times somehow.
