gtow69 hit it right on, I had the same hot Chevy no start blues with my 1954 3100 with a V-6 4.3 and installed a Ford solenoid on the inner fender and ended the no start problem in about one hour without having to wrap or insulate anything on the starter or exhaust pipes, there is a kit sold for this for about 40.00 but I just read the online directions describing the kit and did the whole thing for about 15.00 I have not had a problem since, I hope this helps,
