?! Chevy Starter Doesn't Work When It Gets HOT !?

I agree with shortbus. You need a good cable fron the battery to the block near the starter. A cable from the battery to the frame and then a cable from the frame to the engine is wrong. I've made this change on many cars with the same problem and it works. The first time i did this was many years ago. At the same time I did a tune up on the model A that had this problem. When I went to start the car the engine turned over so fast I thought I forgot to put in the plugs. It makes a big difference. I have'nt had a hot start problem in years. Try it its a easy fix.
