Try this site. www.mortec.com .Has lots of good info.

there should be another number on the front of the block. I think the number you have is a partial vin. In the attached pic, the VO112CLJ is the number you're looking for. It won't be the same of course, but the number/letter grouping should look like that.

Good luck, keep us posted.

If I remember correctly it would be a 4-bolt main 350 truck motor.. I think my new crate motor had the same # on it but would have to go look..

Definitely a 350, look at the "clock" and date code on the back of the block and post if you can. The most usefull will be the last three letters on the pad you see in 68 Stepside's pic above. Get those letters and a date code we can tell you what application you've got.
