This guy also has some other interesting videos. I'm thinking about an M104 swap rather than improving the M110, thoughts?

Bump, I am curious about this too...

M104 can be swapped without much problem, if you can do the wiring, whatever if it's a KE-Jetronic M104 300-24 or an electronic 2.8/3.2 (though you may need extensive wiring work).

Also I don't clearly see what's the problem to hop up old M110. It had a very nice head design, so big power shouldn't be a problem, actually. Plus K-/KE-Jetronic is friendly to performance mods, if it's in good condition.

Cams and stuff ain't a problem.

I own an m110 euro. After I sell it, I'm going to buy another. Its such a sweet engine. Cams, headwork, bigger valves and compression increase. Tie it all together with efi and a manual gearbox. Loads of fun and power with a lot less maintanence
