Default 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.
