My 2c on cranking it to get oil pressure,
I wouldn't do that until.uoure almost ready to fire it.up. engines are assembled with assembly line, which is sticky stuff. Running In oil is piss. If you pressurise the lubrication system, the piss running in oil will purge all the assembly lube. Then if you get any delays before it gets fired.up.in ernest, it'll be getting the hell cold start on piss weak lube. (Especially if it takes a few.goes to make it go for the first fire.up)
