I just started dismantling my 216 out of my 1950 3/4 ton
I did have the engine running before I pulled it and compression was good in all cylinders ( I can't find the numbers but they were all within limits.
All the cylinders look great except for #4 the wrist pin was loose and scored both sides of the cylinder I'm not sure how deep they are .
I believe the original size pistons are installed the only marks on the top are the letter T and the piston position number.
What is the Max overbore I can go?
Can you sleeve these engines
Any suggestions on measuring the damage to see how deep the grooves are
Thank John

Not a problem at all to clean up a scored wall on most engines unless it's really bad. Stock pistons were offered up to .040. | | | | | Joined: Oct 2010 Posts: 44 'Bolter | | 'Bolter Joined: Oct 2010 Posts: 44 | No I'm not sure if the engine is the original
The engine code is HAA364772.
Hopefully I can get a inside micrometer and see how deep the grooves are but they are pretty deep.

I live just south of Chicago can anyone recommend a machine shop?
Thanks
