| I don't want to be arguementative, but cylinder walls that are too thin causing overheating? This just doesn't make any sense to me at all. And what about it getting worse over time? Did you know that many street rodders half fill the water jackets with block cement for added rigidity and don't suffer from overheating? And cement certainly isn't a good conductor of heat. If you are certain that the block and heads are clean, and that the cooling system is in working order, then too lean a mixture might be it. Fuel restrictions in the carb, fuel pump, filter etc might cause this problem. I doubt ignition timimg will cause the problem unless you always run at full throttle. By the way, running with no thermostat can lead to overheating as the coolant travels through the engine too fast to absorb the heat (At least that's what the theorists say). A proper working cooling system should take care of improper engine tuning, hard use, etc. I still think you have something wrong with the cooling. Leaking head gaskets will also do it. As far as percolating after the engine turns off, my 428 temp gauge reads very high when I go to start the car if I've previously been driving it. The heat builds up as it has no where to go. Also, experts say that your oiling system has more to do with cooling the engine than the radiator/cooling system. Have you done any mods that would cause a lack of airflow around the pan? Anyway, good luck figuring it out. I hope it's not the "thin cylinder walls" as that is the most expensive fix I can think of. |
