Ok I'm back and still chasing this problem. I have since replaced the intake and put a new center carb on. And have now discovered that I'm not getting fuel to the carbs.
I disconnected the fuel filter (between the tank and pump) and thought that I'd check to see if I got fuel coming out the line from the gas tank. I did my best to blow into the tank and I was able to get fuel to flow out not a lot but some.
Next, I disconnected the pump and cranked the engine with no fuel coming out. I took the pump off of my other big block (383) and replaced it. I will mention that the pump I took off of the 440 did not appear to be working and had a hole at the top. After replacing that I still can not get fuel to the carbs.
The only thing that I couldn't do was run a line from the pump the to the carbs bypassing the FUEL VAPOR SEPERATOR (I just didn't have an extra fuel line).
Anyone want to put in there ?
Gas / Fuel Tank Sending Unit plugged? or Fuel separator plugged?
