Just a guess.

Mains seem to be a tiny bit lean according to the dyno. A dyno is not real world conditions.

With 55idles how far out are the idle mix screws? If you have them at 2.5 turns then at 2.25 turns it'll run like crap. Adjust all the same. Adjust all the same. Adjust all the same.

Adjust accelerator volume leaner till it bogs then richen slightly till it doesn't. Too rich cools combustion then gives a false sense of acceleration as it lags and eventually zooms.

Air correctors are nice to adjust the mains when in 5th & 4k foreward. At 4k there shouldn't be any idle jet interference. If it feels like it's leaning at 4.5-5k then you reduce air corrector size.

Where the mains comes in varies. Mine come on at around 3.2k and the idles stay with the rpms till around 3.8-4k.

I like to road test in 5th. It should be fixed pedal ok at 3.2k and 4k. When that's nice 4th gear pulls should be perfect.

32 venturis should be fine.

What distributor is installed? What is your initial advance? What is full advance?
