Re: 1950 327 with Ultramatic - Idle Speed

If it idles well at 310, I'd say leave well enough alone, but I might also ask how you bare measuring RPM, because 310 is quite slow and I would think down at that speed the idle would be lumpy at best.

I find to shift into reverse I want to make sure the engine speed has dropped down before I make the shift - don't be in a hurry.

Sounds like you have changed the fluid a few times, that's great. The torque converter has drain plugs, part of the procedure to drain the oil requires draining the converter via those plugs, so hopefully you did that too, if not, next time.
