I have a '70 C20 with a 402 (bored, but don't know how much), 400 trans, AC and tow a 6000 pound travel trailer. I'll be pulling the engine out for a rebuild soon, and was wondering about an aluminum radiator. It currently runs pretty hot, so I'm going to replace the fan clutch with a higher duty one. It has a 4-row brass radiator in it at the moment. I may go to a 454 if this engine can't be bored again. Sleeving is out of the question, given the cost, if it can't be bored again. What do you have for this application

Thanks,
Steve
