Big Chief,

Thanks for the advice.

The engine does run well. I have checked initial timing and its at 12, which I believe is acceptable. I don't currently have an adjustable timing light, so have not checked the total timing. I plan to get one so I can check it.

Gas mileage is around 11 mpg. I would like it to be better, but from what I have read, this seems typical. I had a 200r4 put in to improve the mileage, but really don't drive on the highway enough to see if its any better.

The car does overheat while idling, up to 225F on days when the ambient temp is 85F or hotter. When it gets that hot, I shut the car off, but pretty sure it would go higher. It stays at 190F or lower while driving at any ambient temp. I have tried just about everything to keep it cooler at idle, such as adjusting the water pump baffle plate, mixing coolant at about 25% antifreeze, adding water wetter, replace the 15lb radiator cap, radiator fan positioned 1/2 way into the shroud, flushing the cooling system. I think the radiator is pretty old. Its not aluminum and the tubes inside look like they have alot of deposits, so I am considering replacing it.

Thanks for your advice on the distributor. I'll keep the Mallory.
