I am confused (not an uncommon situation for me).
HAA is the engine serial number prefix for a
1950 216 car engine? Maybe this is an earlier code placed on a replacement engine?
Why would it have an oil distributor if it does not have the oil line going through the block?
The block casting code is for a 1953 truck 235?
Karl, does it have an 18 bolt head (1953 or later) or 15 bolt head (37-52)?
