got a call from the machine shop today. block looks good, they had to bore .030 over to clean up walls and remove taper. crank is straight, gone to polish up journals, said pulley was not secured on the shaft, then we laughed as it is a press fit no hardware to hold it on. babbitt is in good shape. 

have to order my .030 cast iron pistons now and get them to him to move forward, they will hone the bores to final dims once they have pistons and rings in hand.

update, went by the machine shop today to look at the block and crank...

block has been rough bored .030 over, have pistons on the way along with pins and rings.

spent a good hour going over what has been done, where we are, and what is next on the list...

he had concerns on the crank, looks like all the front main bearing area has some wear in it, about .70 or so, you can visible see the low spot of the wear. we talked about grinding it flat and getting it smooth, and then polishing up all the journals. looks like the center and the rear we re previously ground down .010.

crank is free of cracks, and is straight !!

then looking at the mains...

visual inspection say they look to be in good condition ?!? 

think there was about .004-.005 shim in the mains bearings.

should i just get them all redone and start over or ?? considering i have to get the front journal of the crank ground

sounds like a plan, then all the mains will be .010 undersized from stock. not sure what shims were in there. i talked with Russ up at Paul's and it is $365 to do all the mains. i found a local shop that will line bore for me estimated around $650-750, Russ said $625 for him to do a line bore, plus $400-500 for round trip shipping.

think to be safe i am at lest going to get all the mains redone to a semi. then the local shop will line bore and finish it off on the mains with .006 - .008 shim set for each per the info i read for the 194 Chevrolet. think the sets i goat are .031 sets so could do any variation up to .010 per main bearing.

really debating if i should go ahead and get the connecting rods done or go with what i have ?!? guess could mic out the journal for the rods, and then measure out the assembled conn rod sets with no shims and see what allowance i have.  Russ quoted $110 per conn rod re babbitt. do they do these to a finished size per the crank journals or ?? set up with a.006-.008 shim set in each conn rod when doing so.
