Thanks for the replies!
My aluminum block 427 has been intermittently overheating and belching out enough water to cause an overheating condition for the last 6-8 mo's. Had to trailer it for the last day at our "Reptile Roundup"and drive the the tow vehicle .
I'm running a 13# cap, which I though was too low, so I called David K, and he said "don't go higher, you'll blow the radiator", so I changed out the 'stat. No joy, still o'heating.
