Hello,
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
