2 - 1''Row Alum rads Any good

I’ve used champion and griffin radiators with the two 1” tubes. Both worked very well.

I stuck a radiator out of an s10 truck in a rat rod with a 383.... that thing is only about 3/4 thick and cools the engine great with a clutch fan and no shroud. I didn’t think it would work but it does. Lots of factors involved in making a system work
