340 Overheating Help

just sharing info: a quote from the very first post in this thread

"The motor does not crank when it is hot, i have a mopar mini starter on it."

I cannot stand Mini Starters, to me they are all expensive junk!!! IF I was given one I would throw it away. cannot see burdening someone else with junk like that!! IF you at all can replace that mini starter with a full sized SHORT Mopar starter...chances are your car will start hot or cold, unless your headers touch the starter, THAT can be an issue

You are certainly entitled to your opinion, but to me the only reason to keep the old boat anchor starter is to be factory correct or for that Chrysler sound.
Im sure the majority of people on this site recommend mini starters.
There's really no comparison in the starters, performance wise.
Not sure where you come up with "expensive" either. My last 2 cost me $20.00 each at the junkyard.

You either have a bad starter or to much timing.
What is your initial timing set at ?
