I have the 0290 Lycoming and it seems to be working out just fine. Hope yours does as well! Dave (Rocky)

Not yet up and running.  Engine installation went well, however, the motormount that Zenith provides seems to me to have an excess "P" factor offset.  That makes the cowling difficult to fit.  Also the cowling they provided is requiring a lot of work on the bottom half of the cowling.  Have so far taken a good 2 1/2 inch  wedge cut from the rear to the carb air intake to bring it in to match the firewall.  Will see how that works out. 


The 320 E2D dimensions are the same as the 235 except for about a 1/2 " greater width due to larger cylinders.  I have replaced the Lyc starter and generator with SkyTec and that reduced about 15 pounds.  Using a Catto wood three blade prop so am below the 300 pound firewall forward weight that Zenith uses for a limit.


Will have more thoughts on the engine installation when all is said and done.  Have been away from the project for over two months due to bilateral knee replacements.


Good luck with yours.
