1968 Z28 starter overheating?

[Bobg302DZ]

I have had a somewhat chronic problem with my 1968 Z28. Original mo 302 with stock exhaust manifolds. Car always cranks and starts right up cold. Runs great does not overheat. However after a drive of 20 minutes or longer, after shutting it off the starter cranks REAL slow almost like the battery is dyi http://www.yenko.net/ubbthreads/images/graemlins/confused.gifng. It will start. After cooling off for an hour it cranks normal again. Could the starter be overheating and could that cause this problem. If yes. Is there a fix. Thanks for listening, Bob

Sounds like the solenoid on the starter is tired and heat makes it even worse, get a rebuilt starter,or have somebody rebuild yours and that should fix the problem.

My 68 Z also had the same troubles for a bit. I had it rebuilt being the original starter for the car and have had no trouble since even with the hot summer.

Same problem here on my 69 Z/28 I just finished. The starter looked and checked out fine but after further investagation the guts were not hi tourqe that a z should have. We rebuilt it using the correct guts and its fine now, cold or hot.

I had the same problem once and it ended up being the battery. Not enough amps to turn over a fresh (very good compression) engine when hot.
