Starter overheating question

[WILMASBOYL78]

Check your cables like Rick says....then make sure the starter/solenoid don't have any issues...if the starter/solenoid and cables are all 100% you really should be ok...heat shield is good insurance....good luck..let us know what you find.

Just in case, make sure your timing isn't too far advanced too..

Good point...

My 68 Z had the same problem. I put a 8 inch piece of spark plug insulation over the solinoid wires that run to the starter close to the exhaust manifold .Seemed to fix the trouble for me.

A very common problem with GM starters. I used heat shields, changed starters, etc., but nothing worked. The problem, especially if you have headers, is that the heat soaks the starter and the wires. I tested the voltage one time and only 6 of the 12 volts was getting to the starter because of the heat. The solution? Do what Ford did for years, use a remote solenoid. Mine is on the left fenderwall. Now, no starter problems. Here's a link explaining the solution.

Is there a way to avoid this and still get the same results (ie high temp solonoid or ?) I have had the same problem with my 427 over the years, even with new wires and rebuilt starter and heat shield (hi temp fabric).

Also check the ground. I have seen a loose ground cause the same problem. I have used the rigid heat shield on my nova before i put the 496 in and it worked well.
