One last question as my engine trucks off for an overhaul tomorrow. 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
