Recently purchased a Chevy 1950 Pick Up with 350 engine with headers. The starter is acting like they used to back in the day and you had an overheat problem and had to let the engine cool or tap the starter with hammer to get it started. Headers appear to me to need a shield between the starter and the header to cut down on the heat. I'm putting a new starter on just in case and Alternator needs replacing as well, also new battery cables. I'm hoping this action plus a heat wrap on the headers or wrap for starter will help as well.
ANY SUGGESTIONS as to what else I can do. Thanks Rooster
