Do I have this SS combo right? '74 Challenger 360

Hey All

Bear with me, learning the ropes..any and all help appreciated.

A 74 Challenger with 360 car would run SS/LA as its "native" class @ 3508 pounds +170 for driver.

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

Steve
