As far as Continental is concerned, the only difference between the C75
and 
the C85 is the carburetor.  All other parts are identical.  Oh, yeah, the 
oil filler cap has to be remarked to say "full" mat 4.5 quarts.  Of
course, 
the RPM limitation (Red Line) is different and there are necessarily 
airframe specific issues. Prop, trim tab and baffling, in the case of the 
Ercoupe.

Rich:

The C85 is eligible for installation on the C and CD, so there is no LSA 
issue.  It may look and smell like a C85, but it won't perform like one if

you don't have the prop repitched.
