Which Carb to choose for my 225 Slant Six

get the 390 holley, headers into 2 1/4 exhaust, the mp 268*/.460 lift cam and either a 4spd w/3.55 gears OR a 2500 stall convertor/904 at with 3.73-3.91 gears...

and be done with it, until the big valves come along...he he

side note, is this cam the best? maybe not..but it works real good and would especially work in this app.
