r/Chevelles

I'm at a crossroads here, I have a 1970 Chevelle with a SBC 350. Keeping the clutch fan, but curious about radiator upgrade.

I live in Texas and the car has AC, I'm worried about summer heat. I was looking at some 3 row aluminum radiators but the prices are sketchy. How come some are $150 and some are $1,200?

My budget is closer to the sub $200 range, but what is everyone else running
