    Don't know if you know it, Michael, but you 'started' a long
      thread on the Forum about this (Steve Gerow re-posted a link he
      got from you):

    This guy's research, while impressive, has been disputed here:
    This is of major interest to me, as I'll be rebuilding my BJ8's
      engine in the near future.  I've run it on off-the-shelf dino
      20W-50--Castrol, Chevron (mostly) and Valvoline--for almost 120K
      miles so it will be interesting to see what the internals look
      like now (also want to see what deposits, if any, the PCV valve
      has caused in the intake system).  #2 has low compression and
      we'll see if cam lobe wear is the cause.

    Agree with Chris on the cam lube.  I bought a bunch of GM EOS
      assembly lube way back when and I'm tempted to pour a bottle down
      the pushrod tubes before first startup.  Thoughts (of course, I'll
      use assembly lube on the cam and all moving surfaces)?
    Also, I'm leaning towards buying a cam from Denis Welch, which
      they say is 'gun-drilled' which, I presume, means the cam is
      lubricated internally and supplies a stream of oil to the lobes. 
      I'll probably also go with their bucket lifters which have a hole
      on the bottom to supply yet more oil to the lifter-lobe surfaces.
    I'm interested in hearing any and all thoughts and experiences on
      engine assembly and break-in.  I'm going all-in on this
      rebuild--it'll be the last for this car (I hope)--and my dad wants
      a friend of his who owns a racing engine shop to do the major work

        Interesting, but he completely missed the point that a
          fundamental part of most flat tappet engine (BMC A, B, or C
          series) builds that I know of, is liberal application of your
          favorite "cam lube" on the cam lobes, followers etc. 
        Which is usually a molybdenum disulphide based grease
        E.g. http://iskycams.com/cart/index.php?main_page=product_info&products_id=1809
        So the break in/ run in oil is less of an issue in that
          first 5 - 10 seconds of start up, because the cam lube is on
          the cam before the oil pump even starts turning...

              Talking of oil here is an
                interesting article...VERY LONG... on lifter wear that
                is opening some eyes!!!



              Certainly has me

                      We never talk about oil, so ....

                      Anybody use this stuff?


                      This is the best price I've seen on (I assume
                        it's) decent 20W-50 (and I just bought 3 cases
                        of Valvoline @ $4.99/qt + shipping).
