CE on big block

[Tommy]

Does a CE before a short set of numbers on the front pad of a big block designate it as a counter exchange or service replacement engine?? I found this on a # 3963512 block today and would like to know before I buy it. Thanks, Tommy

Could be either, no difference between the two.

Thanks.
