Ditto with v8 engines, which were not only initially fired on propane 
and fed oil through a clamped  fitting that coupled to the oil 
pickup, their valves were adjusted running, and the cranks 
"finish-balanced" that way as well (if necessary), with vibration 
sensors hung on the engine and strobes flashing on the heavy spots on 
the crank, which was then assaulted with hand-wielded machinery to 
remove material from the counter weights until the engine ran without 
vibration.   I saw photos of the line where this was done along with 
descriptions of how it was done, no valve covers, no oil pans, with 
guys who were *very* good at their job, covered in oil doing the work.

I thought it was amazing.
