Roger, I think it's over 100k now. Did Yenko only make 5 ZL-1 motors or did I misunderstand the ad? I thought there were quite a few Yenko crested ZL-1 blocks out there per old threads on this site.

Brent you are right, not sure what is special about this block that makes it one of 5, but Yenko made it with the name embossed, with the crest, in Can Am size or from the original Zl-1 dyes but without dates and numbers. Made em for years.
This guy is just another case of information pollution.
