Off-center block
I know you have been looking for a while. Im probably not going to use this
so I will give you first shot at it. This was a running motor that cracked the crank but did not come apart. The owner felt a vibration that wasnt normal and took it apart. It is 4.000 bore and I have the pistons that were in it.
The front 2 cylinders are broken out at the bottom but it was run that way and shows no signs of a problem. More pics available. $2800.00 plus shipping
I also have a set of brand new 4.005 JE pistons if you would want to sleeve and hone it. Mike Booher Dayton,Ohio cell 937 272-4313
