Double plumper carb or stay with Vac sec carb?

ok spec on setup. 360 .030 kb pistons 10.2to1 comp. run 93/110 oct 50/50 mix J heads ported with 2.02/1.60 hughes engines cam HTL4852s solid cam. 248 252 @ .050 .563/.572 106 lsa. air gap intake,Hooker super comp headers, carter race mec. fuel pump, holley street avenger 770 carb , pertonics flame thrower 3 bilet dizzy with rev limiter set at 6800 , TF727 race built with 3500 stall, 3.92 sure grip 28/10.5/15 MT slicks.
Question is would I gain by going to a double plumper carb on this setup? Other notes for the future is that I might be going to a M1 single plane intake and prob a set of 4.30 gears. for now it is drove on the street but will be soon a race only setup and maybe a cruise on the weekends. Engine is in a 67 notch cuda race weight 3300 lbs. What Ya think? Thanks in advance!
