I have a 69 camaro with a 350 engine and headers. Vacuum is running at 16, installed new distro, plugs, wires, etc and valve cover gaskets but the #8 cylinder gets to about 1100 degrees within 5 minutes of idling. Drivers side all stay within 500-650 degrees, pass side 600, 800, 740, 1100. The starts glowing and if the car runs for over 15 minutes it will not restart. I guess this is from the starter getting so hot. Any ideas why the #8 cylinder is getting so hot?

Thanks,

Brian

 

My SAWG; cylinder running lean, or possibly the exhaust valve is not closing fully or burned out, and lettin combustion fire in exhaust port. Also may want to check coolant circulation in that area.

 

X2 on the coolant. Pressure test your cooling system, I had a 305 with this exact phoblem. Bad head gasket.

 

Is the vacuume reading steady. Almost sounds like an intake leak leaning out that one cylinder. If it is glowing you sill see damage soon if you continue to run it this way.

 

is #8 firing? whats the plug look like?

 

^ How could #8 be glowing at 1100 degrees if it wasn't firing?
The OP is a one post wonder from two months ago, prolly not gonna get an answer anyhoo.
