by all means do it yourself! it will take a little patience, but you can do it in a single afternoon. when i did mine the hardest part was physically taking old one out and putting the new radiator in, but my 79 has all the stock shrouds and intake ducting, etc.  The trans cooler lines were a bit of a pita too, but it was ok in the end.

Tape some cardboard on the front & back of your new radiator when you put it in . That'll keep it from getting damaged on installation.

I replaced my radiator last year as my winter project. Did it my self and I have a 69BB. If you have air, it makes it a bit more difficult.
I removed the hood and unbolted the shroud and the core support. Push the core support as far forward as possible and take the shroud and the radiator out together. I took my radiator to a local radiator repair shop and they rebuilt mine for $300. They saved the date tages and made it look original. When you replace it get the radiator seal kits and replace all the foam seals. I pulled my core support out of the car and bolted the radiator to it and dropped them in together, on a BB the shrould is a real PITA to get out or in. While you are at it replace the upper and lower hoses, if you don't know the history of your water pump I would consider replacing it as well. Replace all the belts also.

Hey Guy's, just wanted to thank all of you for your help and advice in regard to changing the radiator. it took a while to take out, and put in, but it's done. I just wish we did'nt have all of this snow and ice, I would have taken it out for a spin. well the weekend is coming uo as well as better weather

Great job Robert!  

Very good Robert. Nothing like the satisfaction of doing the job yourself. You don't have to worry about what the mechanic may have missed.
