I have dynoed both avs and afb's and the metering is same the only difference is the ability to adjust the secondary air dam which only effects when throttle is cracked open. When dynoing that intake With egts we did not find any cyl that was off from others. Jake

440-25 w/2 X 750's with 119 jets in all 8 holes.
notice the fuel flow #'s on all 3 pulls.
it took that much jet to get the flow 's close to where it was with the 1050 carb on the single plane intakes.
