Well there's not going to be a lot, but 4:10's unless you have a hookup, will be easier to find than 3:92s.

You will notice the difference in et between either set and your 3:55's especially with a locking diff. The problem then will be traction, but with only 188 rw hp ( I figured that here) http://www.ajdesigner.com/phphorsepo...horsepower.php traction shouldn't be an issue until you start making more torque.

Btw I took your weight and hp and calculated your et here... http://robrobinette.com/et.htm

Thanks Al. I'll be looking for either set... Mine right now has the "one tire fire" lol so is that a locking diff or open diff?

It's open... :)

That's open. Id go with a Detroit locker so your for future plans if any. I'll be going 4.56 if I stay natural aspirated it 3.42s if forced induction

Alright thanks guys! I'm working on a deal right now with a guy with a wrecked SST. The "super sport" Ram they made in 97 and 98... I'm hoping it has the 3.92's. I'm waiting for the guy to verify it for me, but I'll be checking them myself just to make sure if he says they are.
