Casting #

[Motor sarge]

Looking at my engine this morning I took a down the casting # on the rear of the block. I am wanting to figure out what year of production this was used. Any other info that may be helpful would also be appreciated . I am trying to decide to see if it will run ? Has been setting for several years. Looks to be all original,I do not think it has ever been apart. This is in Cucv ,35000 on odometer. May be original milage? I am trying to decide if I should remove oil pan and look around? Slight play is felt in timing chain .

Block casting numbers are not specific enough to help determine when it was cast. You could visit the following link, which will help you with dating a block.
