Hope all is well where ever you may be. I have a 1964 ford 4000 with a 172 4 cylinder gas engine. The #2 piston decided to walk the plank and from just below the piston rings it broke off. No major damage found. So I ordered an overhaul kit. I tore the engine down and removed and replaced the cylinder sleeves. My question is do .090" thick sleeves shrink on install? The bore should be 3.90" and I am measuring them at 3.877" it's a small difference but has a big impact on the pistons. The pistons do not have enough clearance to be installed (pistons measure 3.875). I have a machine shop lined up to bore it back out to 3.90" has anyone seen anything like this?
 

Been several years but I'm thinking that engine is a dry sleeve block, if so most dry sleeves come slightly undersize and are final honed to proper clearance.
 

Measure the pistons at wrist pin height opposite from the pins, that should be the widest part of the piston, you'll want the final hone to be .0045-.005 larger than the piston.
Example: if your piston is 3.875 and the sleeve is 3.877 it only needs to be honed to 3.8795 or 3.880 taking out only .0025-.003
 

Post the block casting numbers on the right lower side of the block.
You could be right because after thinking about it I believe the later engines were parent blocks with not sleeves, then at some time in it's life the block could have been bored and sleeved back to standard.
 
(quoted from post at 13:43:24 04/15/20) Measuring the wrist pin I get small .001-.002 variations in measurements 3.877 - 3.879

With that measurement after the sleeves are installed I'd shot for a final hone of 3.884.
Once it's hone stick a piston in each hole upside down and see if you get at lease a .004 feller gauge between the cylinder wall and piston.
