Well I got her done and no leaks and heat back in the cabin and under the hood. I used an Edelbrock # 8607 thermostat to solve my problem. It's the bigger one for the older cars.
I did the same thing. I boiled the dam thing and it never openedMine was definitely failure. Put in a pot of water, 200 deg still only open of hair.
Ha! crackin me up, man. But how true.........ahhh the good ole days.I had a girlfriend like that....
No T stat for me. Restrictor plate is what I use.
It can not fail.
All the T stat does is warm you up and keep it warm at prolonged speed. If you need one you dont run enough compression or timing.
I worry about keeping my engine cool not buying things that get it hot.
