Another overheating situation 63 Slant six

The o-heating started a couple of years ago, after I'd replaced the radiator and moved from the stock fan to the electric as best as I can remember. Its been so long I don't remember exactly.

The thermostat point is on the driver side of the upper tank at the same level as the top hose.

Ill check into the IR reader when I get back from Eastern Wa in 10 days or so.

Once I figure the issue Ill use the correct thermostat, removal has been for testing for any changes in issue only. As I said, I use the pusher fan only because the current and incorrect radiator is installed and it has the cooling coils biased into the engine compartment too far and a mechanical fan is too close to the core, could not even get to the bolts on the fan.

The water pump was from Napa last fall and the coolant is flowing rapido. So much so that as I was inside the car starting it and having left the radiator cap off, the coolant jumped up out of the radiator about a foot when I brapped the accelerator.

I contacted a local radiator place who said they could only diagnose the issue with the radiator in the car and eventually said I needed to contact a place up in Lake Stevens, Stan's north of here.

When I contacted them I asked about getting both the current one tanked and checked and the old original radiator tanked and checked also. I inquired about getting the old one re-cored if the tanks were not cracked and was quoted $550-$650, a tad too far out of my range. If bad I may just have to go the AL route. Don't know what else I can do without spending a ton of bucks and enough already sunk in the the Lil Thang.

Thanks for all the suggestions, any more?
cheers!
