Lots of good info all - thx for the response....

The radiator is new; and I have taken it off and back flushed.....seems to flow fine. I keeps acting like it has air....

- I believe I need to get a surge can on it to give the water someplace to go.
- I ordered a "Cooling System Vacuum Purge And Refill Kit" to try to eliminate any air pockets...
- I plan to drill/tap rear of Edelbrock Intake where the rear water passage hit the intake and install petcock to relieve any air that may be trapped there.
- Sounds like an undersize water pump pulley might help.
- need to check total timing.
- I plan to add two front fans (ERA type); currently have flex-fan with shroud.

There is a lot of knowledge on this forum...thank you all.
