>From my experience from going from VW to Corvair, which is close to the same weight as a Cont, I would get it as far aft as possible, unless you expect an aft CG problem from already having too much weight behind the CG. I moved the fuel from header to the wings in anticipation of having too much forward CG, and it came out pretty good. If I had built the Wing tanks more like Larry did, it would have been perfect.

Heath - Lexington, SC -----Original Message----- I have the plans for the Continental engine showing the mount depth as 11.5 inches. I don't need that much space on my O-235, the Colt mount is just 10 inches. Would it be best to pull the mount back to 9" or is the 11.5 inches about right for a 200 lb engine?
