[Super73]

I will say that I think the right converter is worth more than the gear change.

Example.. I went from a 3600 verter cutting 1.89 60's with a 26" tall tire and 3.73's, to cutting 1.67 60's with the same gear but a 30" tire and a 4500 rpm verter.. The tire change was a pretty drastic gear change, but I picked up .22 in th 60'... It was like going to a 3.23 gear with the 26"tire.

3.73 with 26" @ 6k = 124mph
3.73 with 30" @ 6k = 143mph
3.23 with 26" @ 6k = 143mph

Later I did the gear change. Same tire height 30" but went from a 3.73 to a 4.56. I also took some weight out of the truck. Dead hook consistent 1.60's with a best of 1.59.. Only went down .08 at best.

This recent outing, I was cutting 1.60's. Took my tailgate off which weighs 125lbs, and with No other changes cut a mid 1.5. So how much of the 3.73 to 4.56 change was weight vs gear?
