422 Motorsports rules are directly from the NMCA. For those not familiar the NMCA is the sanctioning body that basically started Nostalgia Super Stock racing in the late '80s. As far as the dial ending in 0, NSS is index racing not bracket racing. Just the same as NHRA super gas and super comp in some ways. NHRA doesn't allow a SG racer to change their index from 9:90 to 9:92 or 9:89 to suit their car. They run on a 9:90 index. Once you qualify at a NSS race and post your index that is what you are locked into. It is and added challenge to this type of racing.
As far as some people on here bashing the 422 Motorsports group, thats fine just don't race with them. At Maple Grove in October we had over 30 cars and it was a blast. If you win the first round you are in the money. They also have a great all you can eat feed for the racers and crews.
They all have a touch of the Philli/south Jersey attitude but thats where they are from. Rich LaMount, Dink Bishop and Fred Henderson are all good guys. They will help you with anything they can at the track. I enjoy beating their cars at the track too but I also like beating everyone else!!!

And by the way, they no longer run a cammer. All of their cars including the Falcon run wedges.
