I have a 1998 300 fourtrax.
Is it possible to fit a 350D oil cooler to my engine? If yes, where do I attach the feed and return pipes? Guessing if it’s possible I have to drill and tap the casing somewhere.

I’ve noticed as I’ve read through threads that some of you fit 350 cams to a 300 engine. Is it that simple? Is there much of a power gain? What do I need to do the mod?

Thanks in advance guys.
