Thanks for all the recommendations, but in the end it was totally my own fault. I forgot that I had removed the nut from the alternator terminal. DOH!!!
I looked at it, but I didn't really check it....
All hooked up and making 14.75vDC
It was right before X-mas, and we were running out to the store, two lane road, short uphill. I had just passed a big box van, but only 45-50 mph, not WOT. But it did blow right as I finished the pass. Temp was low 30's so full heat was on and we had travelled only 15miles or so. One thing that...
The jury is still out. Almost everyone I talked with was "Its a head gasket". I got a combustion gas detector, the blue fluid stuff, and it came in fine. Must have done that test a 1/2 dozen times to be sure. BUT, I'm still not certain of the cause, it was the original radiator.
Bilt, good call. Didn't even think about the fusible link. I'll check the alternator and fuses.
One of my worries was that the radiator was a head gasket issue, I'm glad to hear someone else had the same problem without a head gasket involved.
I'll post what find.

Background to the issues: catastrophic radiator failure, blew the top clean off, 50-55mph going down the road on a normal drive. Radiator fluid every where.
So, get her towed home and in goes the new OEM radiator (ouch) and upper and lower radiator hoses, and some belts...
