351 Windsor

dragpipe · February 11th, 2007, 01:01 PM

Whats up, im getting a 351 from a local junk yard very soon to swap into my 87 mustang. I'm going to first rebuild the engine and all that good stuff. Then im going to hit up a machine shop to geet it bored out to .30" over and get the new pistons. With that done what size gears will i need for the back.

Depends on what you're wanting out of the car. Is it gonna be street, strip, or both? A pretty good middle gear for a big motor like that would probably be 3.55's, though I'd definately lean towards 3.73's if you don't mind the extra RPM on the street.

yeah im def leaning towards strip and street. i was leaning towards 3.73's. i dont plan on adding a supercharger or anything, im just going for all motor. so i think im def going with 3.73's.

what type of transmission do you have and what size tires do you plan on running?

I'd say if you've got a manual transmission go with the 3.73 ratio and if it's an automatic go for the 4.10's.

On a little side note - my brother just rebuilt his 351 Windsor rated at 450 hp and dropped it back into his 95 Bronco. Now of course it's a truck so he's got a bigger rear end, but he went with 4.56s in the back. Awfully good engine you both have, lucky bastards.
