[Methos]

I got talking to my wife's cousin about his 1811 engine woes and said that he heard that the M18 and M22 shared the same block. If it does he would like to have his M18 to the M22 size and put that back into his 1811. If the block is the same what about the crank would he have to replace that if it can be bored to the M22 size? Anything else he would have problems with or should look out for?

Thanks for your help!
