I have a lot of drivability issues with my 69's rebuilt Motorcraft 2100- rough idle, hesitation, stalling on hills, etc. I've adjusted the timing, idle speed, mixture, and most of the other settings, but still haven't been able to get it running smoothly. One of my shops says a lot of the rebuilt carbs are crap right out of the box, and suggest getting a Holley or Edelbrock replacement.
My question is: for a purely weekend-driver, is the 350 CFM 2bbl enough carb for a 351W? I know this engine flows about 580 CFM, which adjusting for volumetric efficiency is right around 500 CFM, but one gearhead swears 500 CFM is too much for a stock 351W and will only increase gas consumption.
I'm aiming for smoothness, throttle response, and fuel economy versus additional horsepower.
