Bolt in radiator for 65 Cuda?

Be careful buying chinese radiators like Champion. Some fit and work well, some don't. They are terrible about the radiators being mounted on the mounting flanges too far toward the engine. This removes precious space that's needed for fan room. I wouldn't put an aftermarket aluminum three row in anything. The modern two row radiators with 1.25" flues are much more efficient. You're boxing yourself in with statements like "I don't want to spend $500...". I would look at the Griffin exact fit radiators, or something from US Radiator. Good luck.
