Cam Duration Vs. Usable/Used RPM Range

Then on your 1-2 and 2-3 shifts your RPM would drop to 4500 each time, not 3850 and 4480....just sayn.:coffee2:

thats why i posted the converter stall, i was just going off the math forgetting the converter slip

if you're shifting at 6500 and your rpm's drop that low you have some real problems. like your rear ratio is 1-1.

i got those using the wallace calculator
