I just ran my first NMCA race less than 2 weeks ago with my Pure Stocker @ Bowling Green..
I entered the the EFI Rumble class and picked the 14.50 index.
Normally a person needs to be a member to run that class but I got a one-race waiver on the membership from "Trey" at the NMCA.
The lady at the NMCA tent then gave me a 5 digit car number (required)and all the letters and number decals for free ! How nice of them.
That '68 Camaro could run the Nostalgia Muscle car class. It is an index based race spaced every .5 seconds apart.
It is a .500 full tree start and transbrakes are not allowed. (perfect for Stockers) Not sure about 2 steps tho.
