Holley 500 CFM 2 Barrel #0-4412S on a Slant 6

The super six you might want a longer throttle cable(not sure on that one), but the throttle and kickdown cables are separate kits. The real pisser on the setup is the bracket for the cables- it is gimp. It works, but it only attaches to one carb stud. The cables will work with your 350/500 2bbl. The really trick thing to do is use the lokar throttle cable hardware on the carb end but keep your mopar throttle cable. Lokar makes a gorgeous aluminum cable bracket but it's for the AFB.

I'm assuming you have a 904 and want the cable kickdown, correct?
