my car seems to rev to high. i believe its because of my 13's. the car has a 350 turbo and it shifts into 1:1 ratio around 40 mph. at 60 it revs at 3500rpms. Would changing rear end gears help? or will i have to swap out trans. Im current looking for a v8 and a 700r4 over the winter...

either or..

a 700R4 has a 0.7:1 overdrive ratio...

what kinda revs does it pull now??

mine hits 2900 RPM @ 60 MPH, with a powerglide( 1:1) and 3.08 gears.

if you tell me your stock tire size, I can figure out what gear you would need to bring the RPM's back to stock..

a 3 speed will always have higher rpm`s at expressway speeds
you can drop a 200r4 in it or a 700r4 and you will have an over drive

REALLY old topic... :roflmao: :roflmao: :roflmao:


(however if ya'll want to see about where your rpm's are ~in case someone finds this with the search and/or IF the search is working, lol) then your best bet is to go here and then here :cool:

So just to be clear? If you drop a 350/330HP with a 350 tranny all you have to do is replace your rear gear to a 2:73 ration and this will reduse your high rev down to stock??

with 13's? Hell no. Get down to maybe 2.41 or 2.14s or something like that then maybe.
