BTW, have you flown
the 185 with the IO-550 mod? Impressive performer. Couple friends have
them for operations in the bush and they do some pretty amazing things
with them.

I have flown my friends with the 300 hp and 8.50's all around, not
enough to get real familiar with though. About this time next year I
will be PPonking mine. That'll give me 275HP, basically putting a
carb'd O-520 in. Another friend just put that in his 180 and he is
15-18 mph faster than me, so if I get another 10 mph I'll be pretty
happy. Went flying this morning and at 4500 MSL I got 152 MPH TAS and
it was warm too, 55F at that altitude.
