351W - Faster
Hi all... I posted this in the Bronco forum, but now figure this is probably better

Any ideas? I've got a 351 H.O.
I feel the need for speed

would be installing lower gears like 4.10's or 4.30's , that will wake your Bronco up!.

I'm thinking about putting 4.10's in my '92 Bronco (351/E4OD). Right now @ 70 MPH I'm turning about 2K RPMS with 31" BFG AT's. Anyone out there know what my cruising RPM's would jump to with 4.10's? Most of the charts I've seen out there are based on a manual transmission in 4th gear which doesn't help when I'm talking about an automatic with an overdrive.

I'm not 100% sure since I haven't check the axle code yet, but judging from the info I've gotten off the forum it's probably 3.55. It's an Eddie Bauer with the factory tow package and dual front shock option. I said I wanted to change to 4.10's in my original post based on the assumption that I have 3.55's now.
