found an engine with a sandcast crankcase Edit.

 I bought 9 cb750's this month to resell to generate funds for my diecast paint job. I'm keeping a few of the nice parts and while unloading I noticed the bottom of a K5's engine is 1002695. I'm going to swap it out for a K4 engine and look for a good head and cylinder block for it. I've got a set of carbs and a valve cover close to that number.

  I already have a complete bike #5511 it's a preservation bike. Not restored but pretty nice. I've put on oem handlebars, it's original rolled rim, a new red seat foam under the original cover and Honda side covers. The rear spoke nipples are incorrect, that bugs me.

"bottom of a case" = lower crank case half ?  if so, then i did not know there are vin stamps on lower crank case halves

Steve,
Don means his newly purchased bike came with Sandcast cases and a later K? top end.

 Yes, sorry I gave a poor description. It's a complete engine with a sandcast crankcase and a K5 cylinder/head. 1002695. 10 bolt clutch cover and K5 carbs too dangit.

 I found two heads and a cylinder. Not perfect but pretty good. I already have the correct rocker cover and hopefully correct case covers.
