69 "CE" 396 questions

[jcwv]

I'm trying to figure out the engine in my Camaro. It's not the original engine as my car is an original small block car. Here is the info:casting number 3969854, casting date J 14 9, front pad stamping CE075672, NO serial number, HI PERF PASS cast into block above oil filter. I know that it is a counter exchange shortblock but the thing that I'm not sure about is the CE stamping. The letters and numbers aren't lined up and are different sizes. I can't get a picture of the front pad stamping because of the alternator bracket. Any thoughts???
