well a while back i rebuilt my boat engine, a 2 stroke and it was my first time tearing a boat engine down, and rebuilding, but i figured to myself that i have rebuilt car engines, 4wheeler engines etc before so i figured the boat shouldnt be hard, well i found the engine has roller bearings for the rod. and main bearings, which recieves lubrication from what litle oil gets to it from the fuel mix of the very thin oil, plus the bearings are packed with lithium grease on assembly, well it got me to thinking, why couldnt' we have v8 race engines with the cam, rod, main and wrist pins with roller bearings and either run a really thin oil, or pack the bearings every now and then? i mean on a race engine that would be torn down and rebuilt on a regular basis anyways, it would free up alot of horsepower if one would do that... i think it's a pretty good idea for a manufacturer to start making these for engines, you could practically eliminate the hp drain from an oiling system, plus all the freed up horsepower from less friction, plus not to mention the extended life from less friction and heat
