Any tips for shifting by time instead of rpm?

We shift on time @1.0 sec. the stop comes on at .05 and off around 3.00 so we are in high gear when we come off the stop which seems to help consistency.

Bill but that is with how much motor.......I'd guess u'd need some motor to be shifting on the stop, or at least that what I've always been told. I'd like to try it but I'm only a 477 (bg blk chev)

Thanks

Almost exactly the same here. Except we go on the stop at .00, and off around 2.25 or so. We shift at 1.0 secs, and the RPM trace on the stop is like a laser line. When we shifted any later, it was much less smooth. FWIW, we have a 565BB at about 900hp.
