[JP1738]

Lenny, that seems a touch high to me. Given its a big block roadster and likely pretty lite, I'd say it won't take much. I try to keep my stuff as calm off the starting line as possible to mitigate the risk of looping the tire or darting one way or another. I have mine set to 4200, but I have quite a bit more gear than this guy. It might take 5k to get it to move with a 4.11 gear, but I'd start low and work my way up if I had to.

I've got mine set up where I have just enough bulb to run .005-.010 delay everywhere I go. Prints 60ft tickets and never gives me the weenie, at least off the starting line.
