Rtoo swap

Well there is no dought its gonna be fast.
What gears in your pete that you want a od like that.

 

I ran an RTOO for a bunch of years. It was a howling S O B in the big hole. The older trans are weak in the back box. If you pull heavy keep it outta of overdrive, when the pitch of the howl changes split it or it won't last long. They have a race car reverse that I never liked. So taller rears are creating more trouble . Not to mention the big hole really gets gearey feeling takes some fuel to turn it but if you have enough motor it will strut. I'm not trying to talk you out of just sharing my real world knowledge of running one for 15 years.

FWIW I ran 3:70's on tall 24.5's. Mine was a factory oo not a homemade.

 

Don't swap to 3.36. I hate that gear. You won't like it with that trans. Won't pull a greasy string.

 

I ran one with 3.90 rears. Ran in 12th mostly. 13th was too fast. Didn't need it till you got close to 70 mph

 

3.36 with low pro 22.5 would be fine with a rtlo 13.

I wouldn't bother with a rtoo .

 

Tall 24's would be close to 3.55's with the lp's
