Tim,
Will a pre 54 raditor hold the higher pressures of a late model sbc if you put a high pressure cap and an over flow on it?
I was thinking of using the original 41 1.5 ton radiator with an electric fan for my sbc conversion.
It didn't work for me, too much pressure. I bought a 4-core from Champion Radiator off ebay. In hindsight I could have got away with a 3-core.
