IIRC the NHRA rules meant a Formula 350 could be run as a Formula 455;
Since NHRA events basically have weight minimums;
an aircleaner - what's that!?
and few vehicles have much of an interior, so who really cares what hood it has(!?).
Come to think of it, I believe NHRA allows any factory classified drivetrain by the car, for the model year - And I have read of cars being run at NHRA events where the model/year of the car didn't match the model/year of the vehicle.
As I have understood it, this is an example of how an NHRA style event differs from this type of "pure stock" racing;
In order to run at PSMCD, your car would have to look the part - so a 1973 Formula 455 (as in SD455) would have to have the correct shaker hood... as well as a full interior.
My earlier example of a '70 Formula RAIV is a completely legal NHRA vehicle, but since zero were built, they are illegal at PSMCD.
