If you think the motor is ok otherwise, I'd replace all the freeze plugs and see what's what. Cost should be less than $20. If one has rusted out, probably others are ready to let loose, too. Take a screwdriver or awl, pop through the center of the plug and pry it out. Remove the thermostat, take off the heater hoses and radiator hoses, get your gardenhose and flush the block through every which way through every which port. Use a small piece of 2x4, line up the freeze plug straight and tap it in until the lip is flush with the block. Too far and you'll impede coolant flow. Then flush it again, and put all the hoses and thermoostat back on.

I (sort of) agree with Eightup (sarcasm aside). The reason I asked about your location is that somebody on this board might have a recommendation of a local shop or might have one for sale close to you. You can use anything with a B-O-P (Buick-Olds-Ponitiac) bolt pattern...not Ch#vy. Shipping is expensive on transmissions and there's not much you can't get done locally or do yourself...even for full race. Ask around the local speed shops (not the McAuto Parts stores) for recomendations on a rebuilder.

FWIW, I'd never buy a transmission or engine from a "prebuilder" that I haven't met...like from the McAuto Parts stores.
