I found the casting numbers on the block the only problem is they are unreadable it looks like someone intentionally damaged the at some point in time.
The date code is G289
Can anyone tell me what the block is that I have does it have 4 bolt mains and what type of pistons did it orginally have... I just want to know if this motor is possibly worth trying to build for more power
