Default Re: 1937-1938, 21 stud engine bored to .125

I am going to sonic test the cylinder walls.

What I am gathering is the 24 stud, 221ci engine that I bored out to .125 has thicker cylinder walls than the 37-38, 21 stud engines?

All of that aside, what about the head gasket question?

Brian, I asked my machine shop about sleeving back to .080 becuase the pistons and rings that are in this engine are new. I would be able to use them and not have to buy new. That is not a problem. The cost rises from $250.00 to bore it another .045 to over $1200 for sleeving and decking. Which is not a huge issue I wanted to try the path of least cost.
