That gives confidence in using the wacker technique.
Contacted the folks at Advanced Sleeve in Concord,Ohio.. the main concern of going from thin wall to thick wall sleeve is a cracking issue.
Maybe the thicker wall cast grey iron sleeve that went into the 50-52 engines had a modified block compared to earlier years to accomodate the thicker sleeve.
Where the 1950-1952 blocks different than the 1948-1949 blocks and when were the thick wall sleeves introduced?
Also, Advanced Sleeve indicated a press fit lubricate is required when installing the cast gray iron sleeve with a maximum .002" interference fit on a 3.368" OD thick wall sleeve.
