A good friend rebuilt his C85 using the O-200 crank and rods. May also need the pistons, I'm not sure. While doing this he opted for Millennium cylinders. He's owned the plane for over 30 years, taking it through many overhauls and rebuilds. He did not believe the upgrade in performance after the rebuild.
I say go for it, even if your crank comes back good. It should be worth a few bucks.

Have any of you opted for the O-200 crankshaft STC on the C-85? My current crank is an ECI .020 STC which is the maximum turn down. The engine has about 900 hours SMOH in the early 1980's; bottom was redone about 500 hours ago (1997) with the ECI .020 crank and bearings (well documented). If the .020 crank comes back from inspection still meeting tolerances any long-term disadvantages for keeping it in the bottom? Would I be better off finding a yellow tagged .010 C-85 crank? Would upgrading to an O-200 crank STC be better long-term? Many thanks, Rich Green N3881H, 1947 415-CD
