Are you building the fuel tank or having someone do it? Make sure you post some in-process photos if it a DIY.
Is true. The biggest issue is the terribly under-sized mechanical fan for such a large c.u. engine. I could go with a six or more bladed fan but, like you, I want to draw as much air as possible through the radiator, since I tend to drive it around town and not on higher speed cruises. The slow stuff just starts heat soaking it and has a horrible time recovering from it. With a carb engine, the gas boils out of the bowls after I turn it off.ctuinstra - making some ducting to force the air into the existing radiator is a cheaper option. It might not completely solve the issue, but it would not hurt.
