Jordan, the biggest problem is the bell housing for your engine has the clutch fork on the left side and a CMP is on the right. A CMP bell housing will not fit that engine. To fit this engine you will have to do some modifications, which is not insurmountable, it just depends how much work you are willing to do. These were good engines and parts are easily available. If this one runs real well it might be cheaper to do the work for installation than pay someone the big bucks to overhaul a proper engine. I have a C60 that was Bill Gregs and it has this engine.
