Is this a ' 71 350 LT1 GM crate motor CEA142837 VO317XCD. HELP!!!!!

The CE at the front is a code for a OTC engine. Sold through the parts department. The engine could be anything from a stock 350 to a 302 to 350LT1. No real way of knowing unless someone has the codes listed for those crate engines. I don't.

I was told in 1982 when I bought my used engine it was a crate LT1 but never could find code in any books or internet search till now. Numbers are CEB12979I V0602XCD. I disassembled engine and checked all part numbers and they are for LT1 engine. I would think code for engine is XCD. You can e-mail me for pics or other information.
