That's why I'm (still tentatively) planning not on a chain but an Harley-style Gilmer (toothed) belt. No lubrication required (or desired). Belt tension needs to be checked every so often -- likely about as often as the V8 will need oil changes. Harleys get as many miles out of their belts as aircooled VW Busses get out of their engines, with no more maintenance than occasional tension adjustments. Mechanical efficiency is good, too, within an hair's breadth of a chain in an oil bath. I'm also figuring there'll be some sheet metal beneath the motors to protect them from road debris, with the front and rear shaped to create an air scoop for cooling. Put a grille and filter in the front and call it a day -- with that kind of protection from the road, assuming proper sizing, the belts should last much longer than on a motorcycle (where the belts are often partially exposed).
