I'm back...seems like the neverending story. Still working on putting together two 25 Sup. K engines. I have three engines...one for parts for the other two. Unfortunately, all the flywheels were removed without being marked...one was my fault (my bad) and the other two by others (they bad). I checked out the "School in Session" for the 29. Now for my problem...my flywheels seem different from the ones described in the "School". Same part no. "344100" but only with markings of "14" and "23" (about 180 degrees different in position on the flywheel). One flywheel is marked as stated in the School in Session with a "UC" and a "25" in close proximity to one another. It has had a new outer ring installed. I have no observation peephole on the flywheel cover on either engine. I have both engines in the #1 cylinder at the top of its stroke and ready to install the flywheel. Question is "WHAT To DO NEXT???
Perplexed in Charleston...not too unusual for me. Thanks in advance for any advice.

I should have said " sp the the 1-4 mark is also at tdc. Reciprocity gives the 2-3 mark 180 and at the bdc along with the throws for cyl 2 and 3.
