Long range is certainly nice as an option… Two weeks
ago my wife and I flew non-stop from Eagle/Vail Colorado to Chapel Hill
NC. 6 hours 22 minutes. Good tailwind to start, then nothing
for the last 700 miles. Total flight was over 1350 nautical miles. The
plane is an angle-valve 360 and holds 52 gallons…
Was certainly nice beating our friends home… their flights
were cancelled, bused to Denver, where their next flight was cancelled
too. Their time in transit was 34 hours. The wife and I were 8
hours door to door.

Thanks everyone for the input. I really appreciate your
taking the time to answer my post. Some solid ideas for me to
consider.
Probably will first try to resurrect my LSE Plasma III ignition
system but this time use the case mounted flywheel sensor instead of the
original pad mounted one that seemed to be sensitive to the heat buildup in the
area of the accessories. Will also try to relocate the computer to a more
forward location to keep all the leads lengths to a minimum. I've always
run Bendix mags.
Already use gap seals but may change cowling openings from the 235
configuration to the 320 style. My CHT's run quite cool, so am
certain there is too much cooling drag.
I'm consistently getting 180-185 KTAS (dependent on
temperature) at 2700 RPM (full throttle) at 7,500' & 8,500' MSL with my 150
HP O-320-E2D and Aymar-Demuth 62 X 78 propeller.
With power settings for 170 KTAS, I have a range of near 1000
NM (6.5 hours) with the 54 gallons of usable fuel at 8,500'-9,500' MSL (7
hours to dry tanks). Have on several occasions flown non-stop from San
Diego to Seattle and on the way back as well (that leg was usually 5.5 - 6
hours).
When the time comes for an overhaul will consider replacing the
engine with an O-360 or 390 and will switch to a CS prop at that time.
This is probably what I really need to do, but my engine is still running great
with very little oil consumption.
