Title: Gear ratio
Post by: Bob & Tracey on October 12, 2019, 02:25:10 PM
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.

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