not familiar with this conversion but I have the article from mopar muscle when they did a spot on the six pack to go setup from Georgia, your linkage may need to be adjusted - I have the original mechanical carbs on my 440 and there is no delay or falling on face, just a tremendous rush and constant pulling after adjusting the stops on the linkage to where I like it. I'd almost say like fuel injection - just instant full throttle response when my right foot wants it. have a set of OE 71 carbs In I will be sending out for a restoration to Scott Smith at Harms Auto (sponsor here on moparts)when I get a box I can send all 3 in. these 4782 and 4783 carbs are fun though - even though the fuel lines and throttle linkage are on the same side(driver). looking forward to feeling how an OE sixpack setup works from the seat of the pants view on my car with auto trans after feeling how my friend 440-6 pack 4 speed feels when he tips in
