i can't help alot with the carb, but can with the trans. at what rpm does it finally shift @ wot. if the rpm is too high, then you need to mess with the governor. at low speeds does it go thru the gears ok? my trans guy says to test the tv adjustment, get the car going about15 mph in 2nd. then floor it, the trans if adjusted correct should downshift.
with the ignition, are you using a hei? if not get one. they are cheap and parts are readily avail. i am running a hei , plugs gapped at 45 and no spark loss.
