I just took the radiator out of my 74 mav to have it rodded out, but the repair guy said it leaked like a water sprinkler afterwards. The crap had filled all the holes. I found a "new" brass radiator on ebay that is guaranteed to fit a 73 mav, but their "does it fit" software says it won't fit a 74. I thought they would be the same. BTW, a 250 to 302 swap is in the works. I believe the same radiator was used for both engines.
