So I do have a 727, tci shift kit, 2200ish stall (needs replaced). 3.73 gears. Had 36 degrees timing trimmed to all in at @ 2400rpm before carb idle procedure. After setting carb idle I'm sitting @ 31 degrees. So I will fix that when I'm happy with idle. Took it for a spin after setting carb idle, goes into drive smoother than before, about 100 rpm drop. Idle is nice, off throttle is responsive. Still not starting easy when warm after the 10 min sit. Ran out of time to play with it tonight. But so far so good.
