I have acquired an original Holman and Moody 427 side oiler block with these markings: C5AE-G date code 5A8 HM number: H47M.
The block has 4 sleeves, and is standard bore. There are repairs to the block on both sides of one compartment down low near the
oil pan, no involvement of the water jacket. Externally, the repairs are not visible at all.
Would these repairs make the block at any risk for failure going forward?
Anyone have an idea what its worth in the stated condition?
This is the earliest 427 side oiler block I know of. Anyone have one with an earlier date?
Anyone know the significance of the "47" in the HM number?
