All you wanted to know to convert a C-85 to a C-90, An A-65 to A-75, and an C-75 to a C-85

Re: Sb m47-16

with this SB, you can put a stroker crank into a C-85 without having to buy a 337, its continental data..and therefore approved

The current c-90 crank is the same as the O-200 and that is what the conversion allows for (c-90) along with the associated part numbers listed in supplement...which includes using the C-90 cam (current C-90 part is actually an O-200 cam)
