Well, first off I would check the timing, just to see where it is. Next, you should inspect the t-stat. A new one should have been installed with the intake, but you never know. You can test the old one, but you might just be better off replacing it with a new 180 degree t-stat from Ford. Aftermarket t-stats aren't very reliable, and the Ford t-stats have a built in "nipple" valve that allows for air pockets to escape from the engine. You should also buy a new radiator cap. A Stant red lever pressure release cap, rated at 16 pounds, would be best. If your cap doesn't maintain pressure, your cooling system will heat up very fast, and can overheat in 10 minutes or less. I would also recommend finding a fan shroud that fits. They do alot more than just protect your fingers. They force the air being drawn into the fan to be pulled through the radiator, thus cooling the fluid inside. Without a shroud, your fan really doesn't do much more than blow air onto the engine. These things should solve any normal overheating problems. Other causes to watch for are improperly installed head gaskets, but since you didn't have them changed, I don't see that as being your problem. If there are signs of water in your oil, you could have a blown head gasket, and should perform a compression check to find out.

BTW, a buddy of mine and I put together a '64 Ranchero a few years ago, and installed a built 306. It had a 180 degree Ford t-stat, a 1972 Ford Pinto radiator, and a single electric fan that was a pusher, and mounted in front of the radiator. It never ran above 185 degrees, even in stop and go traffic.

Take care
