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.
