750 double pump, manual secondaries, adjustable jets

ok , so i picked up a 750 holley, with percy adjustable jets, carb is rebuild, clean and in great shape.

so i need to pick a "jet" size to start with. what is a good starting point jet wise for a mld 460 with wieand stealth intake, 600 lift cam, manual trans.

also, any recommendations on needle setting, and a close setting for the floats, before i try to fire this up

72 to 76 primaries....78 secondaries

bob. the higher the number jet the leaner or richer?

the higher the number the richer
