Gerry,

A lot of unknowns there, engine torque curve, converter stall, etc. I would say somewhere around 4:11, mind you this is just a guess with the info I have for my software. You may need several sets to test with before it's over.

Rear Gear

I agree with Doug on the 4.11. I run a 4.29 gear with my 557 with a 9" convertor(5600 stall) & 33" tall tires & I turn 7150rpm through the lights. Definitely start with the 4.11 with those 30" tall tires.
