Hi Greg…When I was a kid, I put a 402 out of a ‘72 C/10 into my ‘65 GTO and had the same issues even though I lived in the cool So Cal beach area. My “smarter” friend said to put a bigger wire on it, so I wired in 10 gauge wires between a separate H/D toggle switch and the solenoid (cheapest way due to no money)…and never had an issue again. When I bought my ‘72 Suburban from the original owner, I noticed that there was a “Ford” style solenoid installed near the battery…and I believe this also acts as a relay to handle the load going through 4 gauge cables? I have never had a heat-soak issue with the 454, and I attribute that to the solenoid. Nothing to add to your post…just concurring.
