I had contacted Aerosport many months ago. Their quote was considerably higher than the quote I received from Continental. The main reason I am searching is, I hope this to be my last plane (yeah right!!) and would like to have a new engine at least once before I go to the grave.
This plane currently has a narrow deck O-320 that was supposedly overhauled, but I can not find any paperwork on it in the box of papers that I got with the plane. I was sure I had seen them when I purchased it, even though I knew it had been siting a few years without being run. Unfortunately the guy the did all the work passed away and any further inquires are fruitless.
This engine is set up nicely with B&C Rear mounted alternator, B&C Starter, Pmags with auto spark plugs, new carb, custom exhaust, etc. which makes it look like it was done correctly. I really want more HP so have purchased the higher compression pistons. After getting prices on everything needed to bump it to 160+ HP, my thinking was that I would rather invest more, for a complete new engine. I can sell this stuff and recoup some of my expenditures making a new engine not as out of reach.
Trying to keep the plane as light as possible is the reason for the O-340, otherwise I had considered an O-360/370.
