Don't limit your possibilities by what you **think** will work. All too often I find the things that prove themselves are either the opposite of what I thought would work or they were never intended to work as explained by others.

Spinning that bearing unloaded really isn't proving much, because the dynamics change with vibrations imposed by the engine and the timing chains as well as the rapid acceleration and deceleration of the engine. There's a reason why lots of IMSBs fail on the track just after someone zings an engine from a missed shift.

Really figuring this out requires sacrificing engines.
