Lou, what I meant was, when a problem exists..do the basics first before going off on perhaps the wrong course. Gas supply, Ignition timing, Starter, voltage drop etc. Just make sure everything is where it should be. Sometimes a simple adjustment is all you need.
On my car I solved a ton of heat issues when I installed the ford Taurus 2-speed fan, now it runs cooler all the time and I can control heat spikes using the hi-speed portion of the fan.
Good luck, Bill
