Post Cooling Help Please.

My F-1 has a '52 chevy Harrison radiator in it. The size is right dimensionally and has the center entrance from the engine. I'm running 10.3:1 compression 350/383 in it and it is putting out too much heat. Before I built the motor up, it cooled adequately but not now. It will hold its own on the road but a fight all the way in town. I've added a cooling fan and this does not help, acutally it interferes with cooling, apparently the fan itself blocks out cooling area. My engine fan is mounted very close to the radiator, but I do not have a shroud.

What do you guys that run V8 powered cars use for a radiator where the radiator frame is the size of a 50's chevy, a shoebox, a 50's ford or chev pickup,you know that size radiator?

Are you sure of your ignition timing? May be too advancd which can cause heating trouble. How hot does it get? As long as you have a good radiator and 13# cap, 220F isn't a problem.

Willys: No, I don't think I am advanced properly and I know this is causeing some of my problem. The damn motor just wants to idle too high and I have to retrard it to slow it down. I have the Holley 670 Street Avenger carb on it (I admit I bought it because I don't understand Holley carbs....all my experience is with Webbers) and I have backed off the throttle plate screw to slack, so there is no mechanical opening of the throttle plate. Do I now turn the idle screws to slow the idle down? I wasn't sure if this would cause the motor to run too rich by reducing the air flow or if the idle screws reduce the fuel flow. Anyway, I have such low miles (under 500) on the motor that I am concerned with washing the cylinder walls with excess fuel and causing the breakin to disrupted.

Can you help me with this?
