One of Yenko's blocks. That is Yenko serial no.
May also have lp stamped over Winters logo.

My records indicate that many racing organizations did not allow aftermarket blocks, so there were 2 versions made by Yenko when he began production in 1976, one as Yenko and the other to appear to be a Chevy production. the stamp of EK tells me when the block was machined, as I have the code in my records.

I owned one of these, and still own the crate that it was shipped in.
It was shipped from Yenko.
