Gets hot and stalls out

You’d have to have a lot of stuff drawing current to make that alternator cause issues.

I’m running electric brakes, but clearly I was not on them at speed. Fuel pump is mechanical. Really not much else- MSD, radio, that’s about it. Everything else I can think of is mechanical.

Can't help but think the Holley what you call them > double pumpers... 2 outter fuel bowls soaking up the hear from a hot intake and engine.

The difference between Holley and Edelbrock is Edelbrock has the 2 fuel bowls protected under the removable top bonnet plate. less heat transfer to the fuel.

One other thought is the original assembly line 318 blocks hold more coolant than the later re-engineered 360 blocks that use the same exterior casting as the 318 block, so less coolant will fit inside.

So naturally the 360s over heat, then add an overbore and a stroke pushing more power (heat) out of the same block, sorry to say it's going to overheat, unless evasive measures mentioned above are taken.

Good luck on your quest...

I ordered some coolant specifically made for high performance engines that has a 70/30 glycol:water ratio. That should help speed up both heat transfer and flow. I’ll take before and after heat measurements at the radiator intake/outflow and report back.
