SS/LA index is 11.45/7.36
national record is 10.60 @ 125.6
It would be required to run the same carburetor as the same car in Stock class (thermoquad 6453 or 6455S)
It can run a single 4 bbl carb aftermarket intake as long as it will accept a thermoquad? Can a holley intake be modified to accept a thermoquad? Can Intakes be ported in SS - It doesn't address this in the rules for or against?
It would run heads from the same list as a car running Stock class?
Do super stock pistons have to come from the list of NHRA approved stock pistons? The rulebook just says "replacement pistons permitted" and then lists qualifiers.
Also: This makes no sense to me: Dish pistons must retain half of original depth, and original diameter and configuration. Dish pistons must hold no less than original volume, per NHRA blueprint specs.
How could a dish be half of the original depth, original diameter and configuration, but still hold the original volume? What?
Any and all help appreciated.
Thanks

Didn't check your figures, but you can round off to the nearest 5 #
Any TQ that has the same venturi and throttle plate dimensions..Same as stock.
Any intake that keeps the carb in the same location, front to back, side to side.
Yes ,you can use whatever head casting you want as long as it's listed for that make, model ,year.
Any piston that looks something like the original on top, with the correct dome/dish volume.
We can assume that you would want to increase the valve reliefs substantially,as ANY lift lift is legal in SS. Therefore, they would hold quite a few more cc's than stock. Now you can decrease the original dish height to compensate.
Make sense now?
Good luck. That's all I know about 360 Mopars
