I have a 428 stroker built and dyno tuned by Danbury Competition, with about 800 miles. The compresion is 10.5. The starter looks like a standard Ford unit.

It starts fine cold, but when hot the starter drags and barely turns the engine over. It will usually start. If it is really hot the engine won't even turn over until it cools down a bit. By hot I mean normal operating temp and run for an hour or better. The cool down takes about 20 minutes.

I hate to guess. I prefer to diagnose and then repair. Where would you start?
