Not to hijack.... but speaking of water pumps, many years ago I bought one from NAPA (only local parts store at the time). It lasted a week. The next one was bad out of the box. Third one worked, and is still working. The truck was my DD at the time and I was not happy changing the WP that often.

Well, I already hijacked it...that sh...tuff gets old in a hurry, doesn't it? I've had it happen with two crankshafts from the same rebuilder, where they wiped out a rod journal. I don't use that rebuilder anymore.

Did you get the heads and gasket for the 400ci? The ones with the extra steam holes in them?

****UPDATE*****
The culprit was this plastic cap that lodged itself inside top radiator hose. I'll take credit for doing that whoops! Put a heavy duty water pump in anyway. Runs really cool now. It's about 40° here in the Great Northwest. Yes I'm happy.

Oops! Glad you found it and all is well now. Kinda curious how it got in there, though....

I probably couldn't have thrown it down the hose if I tried but somehow it got down there. I more than likely got distracted and it somehow fell in there.

Some new rads come with a plug in the inlet/outlet to keep varmints and crap outta the insides.
Maybe that’s what it is!

Glad you were able to figure it out. How do you like the Classic instruments gauges? I’ve been look at them.

they're ok, wish the numbers were a little bigger but that's keeping with the stock look. My fuel gauge stopped working maybe just the ground. I'll check today.
