Record is 229.308. I assume you want to run 235. The highest rear gear you
can get for an 8.75 Mopar is 2.76:1. With 1:1 in the trans and 28-inch-tall
tires, that9s 7,783 rpm. I assume an 870hp C motor will spin that fast. If
not, you9re kind of out of luck on gears. Next step is 3.23:1, then 3.55:1,
then 3.91:1.
