Cheapskate Cooling...

I put a rad out of a 96 s-10 in my rat rod. It cools a mild 383 just fine, and it was free. I didn’t plan on keeping it in there because I didn’t think it would work, it’s still there, the car has never overheated. I have a large clutch fan on a stock pump with no shroud. The radiator is about 3/4 inch thick. Weird huh
