I'm getting ready to buy a universal alum. radiator (19x22) for my 54 but I'm starting to get worried about it not providing enough cooling for the 350 engine. I planned on a High flow water pump and a shroud for the electric fan but I'm still not sure if I will have overheating problems. The radiators say they are good up to 400hp. My engine will be no where near that. Any comments?
