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

It doesn't have the Yenko name cast into the block , I tought the blocks that yenko made all had the yenko name cast into them ? thanks

Re: zl1 block question
 

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.
