Just noticed that the "Hole Shot 6" car was an NHRA national record holder ! I assume it was in either I/Gas or H/Gas class.
The only real quick straight six car I remember seeing was a 1st gen Camaro. The guy's name was Glen Self. It ran in the Modified Production class. Name of the car was "Stormin Six". He set lots of Nat records & won lots of big races. I know this is not Pontiac related. But a really quick inline six is interesting. And a guy who can build one to set records & win races deserves recognition.
