If it were me, I'd:

1) Check the shroud (got to have one)
2) Check for water flow (is the pump working)
3) Check my timing
4) Check my plugs for lean burn
5) Check compression/leak down for a gasket/head leak.

If it isn't one of those three, I'd check my fridge for cold beer, cause I'd need several to figure out what's up.

Good Luck,

Scott

'65,
Since you are in south florida, you need a fan shroud. If the shroud is there I would next check the thermostat and the radiator. You should have a 180 degree thermostat and a 13 pound radiator cap. Check your radiator to see if it is clogged internally. You may have to drain some coolant. If your radiator has a lot of crud in it, pull it out and have it rodded. This will remove all the crud. Start with the simple things and work your way through the cooling system.

Keeping it really simple, I would run the engine with the cap off first to bleed out any air in the system. Then check that the cap is at least 13lbs and has no leaks. After that follow the above posts.

Get one of those "sniffers" and see if any exhaust gases are leaking into the Radiator. This happen to me, blown head gasket. Car would overheat after about 10 min.

Seems like there was a long discussion on this subject once. But in the old days, it was common practice to run without a t-stat in warm weather until you could buy a new one. I think most of us agreed that the thermostat orifice keeps the water from circulating through the radiator too quickly and also allows the engine to reach a optimum temp in the Winter. It's an integral part of the cooling system and should me maintained.

This would be an ideal time to flush the cooling system. If your stat had barnacles, you have crap inside. Then the radiator should be flushed out at a rad. shope. A stat is nec. Also, living in S Fl, I.m South of you, a 3 row radiator w/shroud is the ticket. I have a 65 cv that has a 4 row-have AC. The condenser robs some cooling. Some time back, a guy in Lauderdale had to remove his freeze plugs and pressure wash out the block, it had that much crud. Our hard water doesn't help.

I live in South Florida and had a overheating problem with my 289. I removed my radiator, had it cleaned, and rodded , installed a five bladed fan and shroud, haven't had any problems since.
