Now I'm gonna need a LOT of help with these old Pontiacs, from guys old enuff to remember those days.
Back around 1961-'62, NHRA came up with some classes which I assume are early versions of the Super Stock class. They had various class designations.
One of the most famous may be the FX classes. I believe it was in '62, when Mickey Thompsons A/FX Tempest won both the Winter Nats & the US Nats.

Near as I can tell, the FX class allowed factory engines to be used in car models they did not come in. An example is a Pontiac 421SD engine, in a Tempest.
Don't know exactly what mods, if any were allowed to the engine. That class sounds to me to be similar, in some ways to the modern day GT SS classes.
If anybody here can give exact details of the early FX rules, please do so.
Hayden Profit was driving M/T's Tempest at the '62 Winter Nats. They actually had the car marked FX/A. Lloyd Cox drove it at the US Nats. The car won the class at both races.
Anybody wanna see some old rules ?

It seems that '61 & '62 were important years in SS history.

Pontiac was still a player in the A/FX class in '63.
