Overheating -- Corrective measure questions.

Update on the progress. I finished installing the FlowKooler pump, Bigger pitch fan, High Flow thermostat, Cold case radiator and relocating the Trans cooler. Unfortunately I had to keep the pulleys that I had from 440 source. Slightly underdriven at .95:1 ratio I think. Today it is 95 degrees out. I started the car and idled it for 20 minutes. It got to 210 maybe 212. I then took it for a mildly spirited drive for 10 minute on the backroads up to 60 but mostly about 45 mph. The temp dropped down to 180 and stayed there. When I got back I then let it idle for another 10 minutes and it went to 210. So far this sounds like a win. I also installed cowl rubber piece and the radiator core rubber piece to seal the hood to cross member.

What temp thermostat did you go with, Kent? Also do not remove that front air dam, dammit. lol That's helping you. It does exactly what you said. Keeps air from going under the car. It pushes air that would normally go under the car back out in front and right into the grill, givin the radiator more air flow.
