307, 305 TBI, 350 TBI, pretty much any motor that came in a RWD B/D body.

You will have to upgrade the trans and rear end depending on which motor you choose.

I would recommend the .307. You should be able to install it without costly upgrades to the drive train, and being that it is less desirable (compared to the 5.7) you should be able to find one on the cheap.
