What gear ratio do I want in my 4104 with an 8V71 and V730?

Can't say, but you must have a 4106 rear end in your 4104. I have a 4.11 in my RTS and can go 80mph @ 2300 RPM's w/ 350HP 6V92TA.

Looks like stock was 4.125:1

Geoff, yes it is a 4106 differential.

4.125 with 12R-22.5 (485rpm tires) with V730 (.88 overdrive). At 60mph you'll be turning 1760. Good Luck, TomC
