Ok since I just picked up a 9" versailles rear end now I'm looking for what to fill it with. I'm planning on a set of 3.25 gears (so I can still drive on the highway) but what differential should I put in? I've been looking at a Detroit Locker, but I've heard that those are a bit to harsh for street driving. Any suggestions? I'm planning on a 351 with about 385HP.

For the street and highway, you've picked a good set of gears. I've 3.55 in mine and it's hitting some pretty good rpm's on the freeway just doing 70.

Definately you want a limited slip differential. For the street a locking differential would be a bit much, gets a little noisy in the corners. There's several different brands out there of limited slip, you'll probably get recommendations for them all. I've got lockers in both my cars, but that's just my personal preference.

well...if you're really gonna be making 385 horse, your already in the "harsh" realm...whats some clicking form a Detroit locker gonna matter? <grin>

Personally...I'll take the clicking from the locker and the knowledge that when I tromp it, its gonna hook. The traction lock's are good when knew but they are "limited-slip" and the clutches wear out.
