I'm sure he left out at least one zero on that 1 of 5 number (and probably more).  I've got a picture somewhere that shows about 8 or ten of them sitting in Yenkos store room.

The "YENKO" script blocks were the first blocks that Don Yenko cast.  I'm to the understanding that GM wanted the Winter's snow flake logo taken off for
warranty reasons.  This block wasn't cast untin 1972 I believe.  So, how could it be a real ZL-1?

Yenko sold a few different versions of the alum big block.
I don't believe the first ones Yenko sold had any Yenko ID cast in.
Yenko was granted permission by Chevrolet to purchase blocks directly from Winters Foundry in Aug 1974.
Blocks were to be machined by Sevakis Industries in Detroit.
This info is from the Yenko estate paperwork.
Yenko sold alum big blocks over about a 10 year period but I am not sure if they were all made and machined by the same companies.
I know there are different versions that have been found.
