Ken, I'm not too familiar with the 944 blocks. Chevy could do a lot of things like that in their engineering department so I could believe it happened. They did not put a 4-bolt main block in the homologation papers for SCCA Trans-Am racing until the 1969 season so it was not legal to run one of those prior to '69. If somebody did it, it might have been very sporadic because I never heard of a car being disqualified for that infraction. Over the cubic inch limit of 305, yes. A Yenko member here had a real Traco block short block that was built for Dana Chevrolet and Dick Guldstrand's Camaro. It was sold to Tomy Drissi who owned the Guldstrand Camaro at the time. Yes, it was a 2-bolt main "657" block.

The actual pins and and then the big ends of the rods were more of an issue than the mains in 1967, weren't they?
If you're gonna get busted for something it would have to be going out of spec in prepping the early rods.

I have a 327 that was built in the 1970's with the Summers Brother splayed billet four bolt mains.
There was a lot of development done on 301 Chevy racing engines before 1967 and was not hard to do a 4 bolt main conversion |

It also could be a mis-remembrance that got recorded....
