.. to that point, how much twin or Aztec time do you have?
It's a remarkably docile and forgiving plane.. they were also fairly prolific for a long time so chances are if you walk into a local flight school and find an old timey instructor they probably have a few hundred hours in one and would love to help you out
My main observations:
(1) need loads of down trim on flap extension.. what works for me is to hold the electric trim button forward as I put the first notch of flaps in
(2) it's remarkably loud on takeoff.. I bring the power to 25 as soon as I realistically can and like to cruise at 23.. I don't find any real speed penalty but it's a heck of a lot quieter. Typical TAS I see, NA, is around 160-165 knots at 8,5 - 10,5 at 23 inches and reasonably leaned out
(3) I carry power in through the flare, ideally I slowly move the throttles back getting to idle just as the wheels touch
(4) at high AoA and low airspeeds I feel a bit of a throbbing or buffet in the yoke, I suspect this is prop wash hitting the elevator. Interestingly I did not notice this in that 310
(5) not sure if this is related to this specific airplane or it is all Aztecs but I find I can't cruise with the cowl flaps fully closed without some CHT issues, I generally have to drag them just slightly open. Oddly enough I can feel a fairly significant pitch and speed change whether they're open or closed
.. makes for a great IFR platform, I have plenty of actual time in ours and it's very stable, sort of just floats over the turbulence ..
Enjoy it!!
