I believe that is NOT an 8.8 rear end... But get gears anyway.

3.73 gears (most major/cheapest mod)
 
Correct me if i'm wrong.... but doesn't that have the "CFI" engine in it? Or was that '86? I know one of those years has the CFI. Cause i looked at one, and i'm not positive but its only on the autos i think.
 
3.73s should be fine.

85's were carb'd cars. Did the previous ower switch it to an EFI? If so, is it a Speed Density or Mass Air system? You'll want to convert it to Mass Air if it not already before you start modding the motor.
