I currently have a 90 RS with 273 gears and drum brakes. I found a 88 9 bolt with 3.45 gears limited slip, and disc brakes. Should I go for this or not. I can have anything off the car related to this swap for $200. Will I run into any major problems when swaping these 2 rear ends?

LT1 motor stuff so far:
TPIS ZZ-9 cam, Comp Cams 1.6 Roller Rockers, Comp Cams "R" Lifters, Crane Cams Dual Valvespring kit, Underdrive pulley, and an air foil.
383 LT1 Stroker project has begun.

 

I'd say is was a pretty fair deal. The 3.45s seem hard to find. Apparently the '89 and later brakes were the good ones (PBR), but that shouldn't be a difficult upgrade if you find it necessary.

I'd do it, but I would look for a set of 89-up rear brakes to put on it even if those 88s work fine. You could always put them on later. I picked up an 89 9-bolt with 2.77s with the complete brake setup and I'l swap to 3.27s when I get to it.

 

The problem with putting early brakes on the '90 and up is you have to change the whole parking brake mechanism.
