What would the best radiator for my 1980 c3 with a stock 350 and a 350 auto? Which is better a 1 row aluminum or a 3 row brass and copper?

 

Personally I would go with the brass and copper radiator. You could also get the regular 4 Tube Corvette radiator and slip in there. It would have no problem keeping it cool.

 

As it turns out, I had my Radiator cleaner out and repaired by a local radiator shop. Now what I have a that is original 4 row that is tip top shape.

Thanks for the reply.

P,S, The shop was Ideal Radiator in Sacramento, Cal
