    You can swap around any f series gears.

    I have 4.1s from a lexus for sale but thats well shorter than your needs. If you decide to rev the engine 3000rpm harder let me know, haha.

    yeah ra65 auto is 3.7 from my searching, As is RT142 IRS Auto. Just turboed the thing and with the 4.1 it eats gears wayyy to quick! Dont wanna rev it much past 5500 it will just kill it
