I have a 383 sbc stroker running 10-1 compression and when I start the engine cold it turns over OK and starts. If I try to do the same thing after the engine has ran for a while the engine starts to turn and stops and starts and then there is a loud mechanical sounding noise, it is kind of like the same noise you hear when you try to start your car and it is already running. The starter is a stock AC Delco starter with a new bendix and relay. Do you think the problem is from heat soaking the starter? Should I buy a starter with a some more power? My battery is a red top Optima, so the battery should be powerful enough. Any thoughts?
