yes but this same rad did cool the car, now all of a sudden running hot, surge at cruise, heating at idle, and it DIES at 190-195????



You definetaly have other issues . 10 or 15 degrees from the "magical" 180 mark souldn,t cause your engine to stall out .

Have you ever tested the fuel pump output?

It Could also be a weak igition box etc.

I,d try that new fuel pump and go from there .do a flow test on it to Make sure the fuel line /filter /sock aren,t partially clogged up which will be more apparent at operating temps . Also some 440 cars came factory with a fuel vapor sepertor which is basically a return line which couldn,t hurt . Most parts stores carry fuel filters like this but you would have to run a return line back to the tank.

Wouldn,t hurt to ditch that edelcrock carb either
