I have a 79' GMC 3/4 ton 4x4 with a 0.060 over 350 and headers that I'm having hot start issues with. I have relocated the starter solenoid to the firewall, but i still have the same problem.

I built the engine with too much compression for pump gas, but I've been driving it that way for several years and have pretty much thrashed a few pistons from detonation. When the engine was fresh, I didn't have the starter problem. I've changed the starter once and it didn't seem to help much. Any suggestions?

You could try a heat shield between the starter and the headers or you could try some header wrap on the headers in that area or you could do both.

Buy a high torque mini starter they work great.

Thanks for the advice fellas.

I installed new 2/0 battery cables and bought a 750 cold cranking amp battery.
It is working great so far, but the weather hasn't been hot lately. I'll see if my fix was successful next summer when it is 100 degrees.

I believe the cables were breaking down and that was the problem. That would help explain why I didn't have this problem when the engine was fresh and the cranking pressure was higher.

Hot starting problems are usually due to too much advance in the ignition timing .......

Another cheap trick you can do is..........Install a shutoff switch for your coil. That way, you can get it cranking without ignition and then click it on........

It,s also a good anti theft device, if the switch is hidden.

i always put a heat shielded sleeve over my cables, seems to help.
