Blueprint 408 cooling system questions.

Wow. I’m sort of impressed and overwhelmed with all the advice everyone has given on here. So it’s finally getting warm enough in Colorado, and as many of you predicted, there isn’t a big change in operating temp. I removed the hood, and it did make a difference. But after long drives, it still gets to about 205 ish cruising. The next logical step I think is the lighter advance springs, and hopefully, that helps. The Engine came as a long block, so no water pump, or intake even. It still does diesel in hot weather, but if you let it idle a bit before you shut it off it seems to not do it. Another problem I have is I can’t get the carburetor properly dialed in even with the timing at 16 degrees. I have even drilled 1/8 inch holes in the throttle plates, and I still have to open the plates too far to get a stable idle. Another problem is it seems to run out of fuel really quickly when you step on it hard, and it’s only when the engine is hot it does that. That clear fuel filter before the carb is empty while running. I don’t know where to start on this honestly.
