# Parts For SaleNEW PRICE!! 2 lycoming O-290-G engine cores for sale. $1500 for both. ### Help Support Homebuilt Aircraft & Kit Plane Forum: #### fixnflyr ##### Well-Known Member NEW PRICE!!! I have 2 Lycoming O-290-G engine cores for sale. I got them in a package deal when I bought a Volmer VJ-22. These engines have the same Crankcase castings and the same crankshafts as early narrow deck O-320's. They could be converted to 150 HP very easily. Just bore the cases out for the bigger cylinders and bolt the O-320 cylinders on. They need overhauled. One engine is disassembled and the other is still together. Not many accessories, a starter and fuel pump between the two. I don't need them, They need to GO. Located in Savannah Ga. Pick-up would be great. I could truck ship for extra money. I really don't want to build a crate but I could for extra$ to cover the expenses. PM me and I will discuss and send pics.
Thanks
P.S. These would be a lot better and easier to get going than some auto conversions would.

The lycoming GPUs had a plug in place of the 2nd spark plug

You forgot to mention needing a new crankshaft as the flange on the 290 is way to thin and full of holes and the need to drill the case for hydraulic lifters in addition to boring the cylinder holes.

The only 290 worth conversion is the -D2 as that came with hydraulic lifters.

So 4 new cylinders, 8 new lifters, new cam new crank plus machine work.

Just buy a 320.

There are a couple of versions of crankshaft flange reinforcements suitable for non-aerobatic use.

In building my 290 engine I used the G model case, cam and solid lifters. 320 crankshaft, 290-D2 cylinders and pistons. 320 oil sump, accessory housing, carb. 2 into 1 exhaust with no muffler. Sen- 74"x 56" pitch at 2900 rpm at WOT. Great engine in the 700+ hours I put on it.

The one together has the aftermarket reinforcement plate. I always wondered about putting one on a 320 crank for aerobatics. The other engine looks like the start of a conversion. My 290G has a D crank in it. If I was building one without parts it would have a budget 320 crank that tend to show on eBay. Something like a STOL plane or a Tailwind would be fine with a G crank and reinforcement plate. It’s not 1963. Solutions are out there. If I was in the market I would be sucking them up. Single seat biplane or other low budget plane, they are perfect.

I used to have the flange doubler and all the parts but haven't seen them for several years, must of given them away, or they are hiding somewhere in a box.

To much junk. Hanger needs a good cleaning out. There is also a new set of 6:00x6" tires hiding somewhere in the same box. Also when I built the hanger and moved into it, I moved a box with a tin metal box inside full of 1800's silver dollars. Hope I run across them before I die.
