Hey Challenger  ..........thank's  for your reply.

Guess everybody else flaked

Well  ....many of you had great answers.......

Anyhow I observed 2 or 3 problems here.

1. The operator attempted finished size to be at  2.938.0......Operator must not have had bore guage correctly
    calibrated as finished size average was  2.939.0 and then some...........

2. mains must have been pretty bad...as at the parting line the block was peened very heavily.
   My thoughts...too much material removed off the main caps w/the cap grinder to try to bring back to size.

3. The mains were not " Bored " and then honed to finish size."......Honed only...(Too much material to remove for
    honing alone ! )


Finally........It look's as though the stones were worn causing the tapered effect, as well as not rotating the block
during the honing process..... and not enough cool down time....I practice getting sizes close, cool down then go back
the next day, re-calibrate mics. and finish to size.
For those of you who have ever resized connecting rods....the process for main work is very similar........................

Just MHO....    

So besides being out of round, tapered and oversized to boot?  Were 4 and 5 ok or progressively worse?

4 and 5 were worse............and i can tell ya why 

okay.....  i don't wanna be a drama queen , ...but:...( Housing  Bore  I/D )

I had a customer come in today to get a second opinion on some block work that he had done at an unknown shop,

Soooooooo.   I do my thing....... I set up my Mic's. @   2.937 5/10....and inspect the mains.

I find the main  housing to be as following:

#1..... 2.938.5  to 2.939.....and tapered.  ( .001 .5)

# 2.....2.939.      #3.  2.940........     okay    anyone see my point........             GT...whatcha think

What is it with you chebbie guys Don't you know that duct tape works better than electrical tape. So I is waiting on parts and thought I would take apart the steering to find out what is making the blinkers not turn off and the turn indicators not work on the dash, and Lo and Behold more elictrical tape

More bla.bla........i did not do that....geez!
