That's because back when I started racing, the only 2 sources of Pontiac info I knew of were Nunzi on the East coast & H-O on the West coast.
I bought all the H-O material & some of their parts. They had helped me with info for my Stocker builds. Their '74 SD455 Bird set a new nat record in SS/KA. Their record time looks real slow, compared to today's SS cars. But, at the time, they had the quickest. Stockers now go quicker than the same SS combo did back then. But ya'll know that.
We saw the H-O car run, at the '78 Cajun Nats. Sorry that we didn't get any close-ups. Don't know why, since we did get a close-up of Sonny Ray. Sorry for the poor quality of the pics. But hey, it does prove that the car was there.
H-O also had a white '74. I've read that the red car is now the car that J.B. Clegg has. He has run well into the 9's with it, as a stick car.

Back in the old days , Super Stock did not allow ported cylinder heads . It is hard to race a SD 455 due to the ported head rule . Most of the cars in the same class have engines that have very common , easy to get cylinder heads . There are only around 3000 sets of SD heads even made, including service heads . The price of these parts is super high , and frankly there isn't a whole lot of head porters that can make them work . Much easier to buy a dozen sets of Chevy heads and experiment .
