Congratulations to the new record holder. Competition only makes a class stronger. CS has a lot going for it and should attract more racers than it does. It amazes me what racers can do with these small displacement engines.

If it has a GM casting number is it legal, Not talking about the SS/CS class.. the rest of the modified classes.
But would it have to be approved for SS/CS?

It's aluminum, so no for SS/CS. Inline iron heads only.

Adger,
The cylinder heads were casted by Dart for GM.
They would be legal in SS/AS and SS/BS, SS/TA, SS/TB, SS/TC and SS/CM thru SS/FM
