firstly how tight do you do the input flange nut that clamps the bearing?(or whatever you want to call it) lock shafts up anf torque?

and also how do you guys run your engines in ie oil grade and changes, grind on the big ends and polished mains new rings. i normally just use chap oil for the first few hunderd miles and do about 800 miles but with this costing an abnormal amount id rather hear different views! cheers!
