If you know about distributors-read this.

Wonder if something is wrong with the torque converter or the fly wheel teeth? maybe the flex plate is binding up or loose? you sure you trans lines are good not kinked maybe the trans is overheating and causing some of this?

Just throwing some thoughts out there.

My problems sound similar to yours. I just installed a new Mallory System - 4757701 Unilite, 8mm wires, coil, ballast because I could not get my car to start when hot. Cold? Two pumps on accelerator and bump the key. Hot? Crank for about 15-20 seconds with accelerator pumping and I may start eventually. My motor is stock so I set tried to set the initial timing at the recommened 2 1/2 BTC. I've read some of these posts where people are setting the initial timing at 15*-18*. My car does not seem to like that. Am I understanding properly what you guys are saying? With vacuum advance unplugged, car at idle and setting the timing to 15* BTC?

Timing

Don't forget that what you're looking at is "coolant" temperature, which does not necessarily tell you starter temp or carb temp or various other underhood temps.

If you read the article I referred to you, you'll see that retarded timing at idle causes unburned fuel charge to leave the cylinders and burn in the exhaust ports and headers, raising their temps dramatically...headers are next to starter, right...

I'm only trying to help and I've been down this road......I've got my own box of near new electric fans under the bench.....

I've run the car both with and without vacuum advance and it carries a lot more heat with out the advance....I even leave it hooked at the drag strip...

Good Luck

Splicer you really know your stuff. i have read your comments and I must say you have your veteran stripes. At best you can bring a horse to water but you can not make them drink. Another way to help is using an infrared thermometer and look at the temps while running a vacuum distributor. You will see a 50 degree drop in exhaust temp with proper idle timing.

This is great info, let me know if you sale your car. I live in the cold country so should not have that problem.
