Old newbe needs help

[Royal Ryser]

I sure have received some good advice here. Next week I will follow up and see what I can do with the problem.
Hopefully, I can make contact with a good mechanic nearby.
Thanks to all.

They have an extended impeller pump available for the Thunderbirds. There is a baffle available but the extended impeller should do the trick. Clearing out any crud from the block is a whole other problem. The belt alignment is what caused the need for that pump spacer so that slowed the pump flow down.

There is an improved T-Bird pump spacer available that significantly improves flow thru the water pump.
But it isn't inexpensive...
