Well I did it!

thanks for the info Scott. You had me confused there also but now it made sense. Bigger tire with same gear should lower trap RPM. I think based on what happen with your combo the 4.30 should be leaving the RPM right about where I want the Engine to be in the traps with a 30" tire. Just got to order them now$$. I can always bump up to 4.56 if it doesn't work out.:cheers:
