Hey guys! Any of you had any luck with the QFT carburetor? Thinking about getting one but the question is if I should stay with the kind of setup I have atm (4150mechanical,dp,no choke, 850) or take another turn, say vac-sec? I have a feeling that most of you guys running holley style carbs use mech-secondaries and above 800 cfm? A dealer recomended me a 750 vac but Im thinking it may be too small even for a mildly tuned (buick)engine. By the way: 455 stg1, edl perf, Lunati 33304, TA-Headders, x-pipe, stock conv( ), 3:90
