59 block questions
I was confused by this block I picked up: it has “59” stamped on the bell with the narrow lip above the cam cover. It is relieved too. I found an older post which our friend Walt commented on:
Walt Dupont--I have had a few of those engine in my shop. They have real thick cyl. walls. The only thing I can figure is there a replacement engine for the 39-42 221 made in 46-48.
One of the sites I read stated that the serial number was stamped on blocks as required by local regulations. I have another stamped 99a xxxxxx block out of a 46 Mercury with the same physical attributes.....any thoughts on the 99C xxxxxx prefix?
It has a crack.
A couple post I have read regarding cracked blocks describe the typical crack from one of the center exhaust valves into an adjacent cylinder as being a tough crack to repair. Can this area be successfully repaired?
any thoughts on criteria for evaluating go-no go to salvage the block before extensive cleaning and further testing?
Is this area solid cast in between the valve cup and cylinder?
(I will add photos tomorrow...)
