Yenko Motor Stamp?

[bulletpruf]

Fellas -

If someone was to have Yenko do a dealer swap on an engine - pull out the original engine and drop in an L88 - what would they have stamped the engine with? Would they also generally have stamped the tranny? Does anyone have pics that they can post or e mail? Guess the only way to document something like this would be a Yenko receipt, right? Not a COPO, so a build sheet won't help. Did Yenko keep records of items like this?

Thanks in advance for any info.
