We had an O-300 in ours and decided
to replace it with a O-360 (180 HP). Glad we did. Continental doesn't
make the O-300 any more, and the extra 35 HP is great. It's a little
expensive (somewhere around $32K) but you get a factory new engine. I
love having the extra power and getting to keep the manual 40 degree
flaps. (Ours is a '64 E model.)

I have a '67 and when the time comes, I will probably upgrade to the 180 hp.
How much more fuel do you burn now? Did you install any new fuel tanks or do
you still carry 36 gallons?

I was up today for 1.8 and burned only 14 gallons of mogas. :-)

As a rule of thumb you can use a half a pound per horse power per
hour.

i.e. 75% power of a 160hp engine is 120hp, so .5*120 = 60lbs per
hour, or 10 gallons an hour in cruise. How you lean, and other things
obviously modify this number somewhat, but it's a good rule of thumb.

HTH.
