Skip, the Crower rods simply keep me from getting that "pucker factor" when we spin the big 455 up near 6000rpm's, I sleep better at night too!
I've tried shifting at at every rpm between 4800 and 5800. There is less than a tenth to be had between those points, so I simply shift at 5000rpm's for bracket racing. It also give me some room to work during the run, if the car slips a tad on the launch or I don't think my RT was that good. I can "buzz" the engine a bit harder and make sure I get to the end first, not giving my opponent any room to back off the throttle.......Cliff
