Well i have tried a few carbs and none really made me happy , frist i had a 650DP witha a profourm main body and it made awsome power when u kicked it but rideingaround it flooed like carzy , so i got a 670 street avanger and it dose awsome when you are just rideing around and cranks good but i hate the way the 2nd came in and done really have a strong bottom end , so i was thinking a brand new stock 600 dp would do me good? or sould i just try to rework my 650DP?

my motor mods are
302 ci bored 40 over,10.5:1 total compression ratio; comp cams XE274HR cam .555/.565 lift; 1.6 roller rockers Scorpion; victor jr intake with 1" phenolic spacer; procomp aluminum heads (ported and polished) with 2.055I, 1.60E valves

What are your supplying fuel to?

The car has a 302 making near 500 hp, dont think stock can touch.

You might know this, but a true dp is a mechanical secondary. Just because it has a place for two fuel lines do's not make i a double pumper. The 670 is a vacuum sec. If the other was a true dp, it sounds like your sec. were out of adjustment. I have been fooling with my hp 750 for awhile trying to tune and adjust, that may be all it needed.

You already have the 650DP..... it's a matter of reworking it and fixing the part-throttle flooding (check those floats, or replace them) and tune it.
