After doing quite a bit of research, as of right now, I think the winningest Super Stock Pontiac A-body, in the modern era, must be the Sonny Ray '72 GTO.
For the SS Bird, I'll have to choose the Ken Shawver owned '78, that he & Monte Howard drove.
For the Pontiac powered GT car, it has to be Phil Monteith's Hatari, because Peter Biondo won so many races in it.
If ya'll have different choices than me, please post that info & tell why you made your choice.
As for back in the '60's, I don't know. Arnie Beswick did lots of racing. But he got off into match racing & some wild funny car type rides. So, up thru 1970, which Pontiac would ya'll say did the most winning in what could be considered Super Stock ?
And, what about nat records ? What Pontiac powered SS car has set the most nat records ? Carroll Warling's '74 A-body is the only record holder I know of this century. Any others ?
I assume there were several back in the old days. Seems I remember seeing a string of years that one big wagon held the record. I'll post the pics again, & ya'll can tell us if you know of a Pontiac that set more records, or held a record longer.
