Here are a few thoughts...

Are you running foam in the fuel cell? Could there be a possibility that the hose that runs down into the fuel cell has curled up towards the drivers side and is not picking up fuel properly when you go into a turn?

Fuel filter could also be partially plugged. When running in a straight line fuel is level in float bowl but if not enough fuel is getting into carb then when you go into a turn the fuel goes to one side of the bowl and engine can't get enough, starves for fuel, which leans out engine and causes temp to rise.

The fuel pump might be getting a little weak which could also cause the conditions described above. I've seen a weak fuel pump make an engine sound like it needed bigger jets, but all the jetting in the world can't correct the loss of fuel pressure.

That's all I can think of at the moment. Hope this helps you out. I'll post any other theories I have if they come to mind. Good luck!!

Just out of curiosity what type and size carb are you running?

OK with the problem occuring at the end of the straights too it's starting to sound like a jetting problem. What do your plugs look like? Do the tips of the electrodes look white, tan, or black? I've also seen a car act similar to this with a BENT float. Setting could seem ok but if it's bent it could be hanging up in certain situations. If the float is plastic the bent float theory is blown away but I've also seen a plastic float get an indention worn into it where the float tab contacts the needle valve. This can cause the float to not operate smoothly and maybe even hang up. Just a few more things to check AC. If those plugs are white on the tips go up at least 2 jet sizes. If it ends up a little fat you can always drop down to the middle. I hope this helps you!! Good luck!!

you might have found it there i had two wire touching last week and i noticed i did run a little hotter than usual one other thing does it do it when you are heading straight or when you set it for the turns mine did that a couple weeks ago would die when the car rolled into the turn it was a pinched fuel line

how big of spark plug gap do you have? if the gap is to big the engine will miss at the end of the straights

I had the same problem. Couple of plug wire boots melted. My problem was my cam lost two lobes and wasnt letting the exhaust out! I got lucky and had a cam ordered allready before I found it out! The new cam cured my problem and luckly didnt cause any major damage.
