I'm going over the finish line at 7300 and would like to see it around 66-6700 rpm.Could this be done by going from a 31 inch tall tire to a 33 inch tall tire??
Would also like to loosen the stall but that would increase the RPM at the stripe.
Now have a Dana with 4:10 & 31 inch tall tire. Peak Tq is around 5000 RPM and HP is 6200


HEMI-ITIS has no cure.
My condition is fully BLOWN!!
