I am starting to assemble my motor.I just noticed the rear main cap bolts don't have lockwashers on them.Did I misplace them during teardown or are they not used on the rear main cap like the other 4?

  

No lock washers are used

Thank you Paul! Now I can tell my wife to stop looking-on Friday!

  

Just my opinion but I think lockwashers are possibly the worst thing you could do to a main cap bolt.  It was old thinking that has been gone since the mid fifties.  I think it adds another place for a bolt to work loose and could/does prevent proper torque and bolt stretch which really keeps the bolt tight.  I would say get or use good bolts and throw away those lock washers.
