Just finished thoroughly check the carbs.
See how much larger the boosters are on the center carb. And the Venturi is larger also. Center carb is off a chevv327 the front and back are 283.
The outboards are rated at 278 cfm and I would bet that the center is at least 315 cfm. I don’t how to measure venturis for approximated cfm so I could be underestimating the cfm. So, that would be 871 cfm plus all I gain by choke removal and grinding out the metal the air cleaner stud attaches to for a total of around 900 or more cfm. Depending on how cfm was calculated
Wet/dry , it could be 800 cfm which should be perfect. I may leave some hp on the table as the runners are not equal. Can’t wait to try it out I had a bud who had a gto tribpower. When he’s was WOT you could hear it for blocks, and everyone around quickly to see what that roaringly delicious noise was.
I’m going to tune them in and compare them with a modified 750 double pumper, at the track of course to get true readings not just seat of the pants feel.

Just as a Mopar six pack the center carb is larger than the outboard sizes.
No. Mopar 6bbl./6pack had a 350 cfm primary carb and two 500 cfm secondary carbs, for a total of 1350 cfm (when measured at 2 bbl. pressure drop- if measured at 4 bbl. pressure drop they came in between 960-990 cfm).
