The C6 is kind of overkill for a small block Ford unless its 300+ horse power. There should be some radiators out there that would work for that application in a 59 square top or do you already have that & just want additional cooling?

I've towed long distance with a 302 a quite few times and came to the conclusion that bigger is better. I was towing helicopters and empty fuel tanks on trailers. I wouldn't use anything less than a 351 anymore.
