    I found a good running DI V2203 for cheaper than the 134 rebuild. I'm likely gonna try this out.

    Also with a turbo these do about 70-75HP, which is about a 50% gain in HP during the usable band of an Fhead - which is about the same as this Kubota. No added weight, and fits in the same spot as an FHead with minimal re-engineering.

    FYI my Roxor has roughly 90-100HP right now and it scoots. No lacking in power. Dropping 500ish lbs and 20ish HP and I'm sure the CJ5 will perform admirably. I need it more for farm type work than 1/4 times.

    Keep in mind the Fhead makes about ~50HP NET at 3000 RPM. The LHead does even worse. Don't mix and match Gross vs Net ratings.

    I spent effectively 0 time above 3k RPMS when this FHead was running.

    My question is what would be the top speed on a Kubota swap? Would it make the flat fender more freeway friendly?

    Top speed would not be driven as much by engine power and wind resistance. You'd wanna make sure your gears/tires/etc/etc are setup for whatever speed you wanna hit. The faster that is, the more you run into steering/brakes/stuff. It's a whole package. A turbo'd V2203 seems like it can output around 75HP if setup for it, that is an nearly 50% increase in power within the sustained usable band. So you're mostly removing a bottleneck without to much re-engineering and keeping the tractory 4 cyl feel. I found an engine. Haven't had time to fart with it yet.
