It seems like upgrading a J3 to a C85 engine is much more common than upgrading to a C90 engine. What are the reasons behind this?

As far as I can tell they are virtually the same weight. The exhaust/cowl mods required over stock are the same from what I have read.

Seems like C90 parts might be easier to come by.

Thoughts?
