My radiator is leaking some. Has a crack at the filler connection. It is a HD rad. out of a 3/4 t truck and seems to cool the 454 ok so far and I do not have a shroud as the one from my 350 is to wide. I want to go with an electric fan setup and thought I would consider upgrading the radiator at the same time. What are you guys with a BBC running for a radiator and electric fan? model and partnumbers would be groovey if you have them.
