Another round with a ZL-1 prototype block????
 

About a month or two ago, we were discussing a ZL-1 block
( boat anchor ) on eBay that existed in its raw as-cast
state. That block went for $1,800+, I believe. Well,
another one has found its way to eBay. This one has Wayne
Guinns name displayed prominantly.

I recall asking if that previous ZL-1 rough casting block
could have been a prototype because the Winters logo was
somewhat unique ( standing proud on a hexagon base ).
Well, it seems that the seller of this new ZL-1 block is
hinting just that.

Check it out. What do you all think?

ZL-1 Prototype block?

Wasn't there was more attempts at tall deck alum. blocks....even complete engine(s) for Can-Am? . Looks more than unmachined....filled cooling passages?

At least some of the Yenko aluminum-blocks also used this Winters logo.

Yenko-logo on the same block.

Anders,

A Yenko crested block with the Winters logo as well? I
thought I had read somewhere that when Don Yenko took
delivery of the remaining ZL-1 blocks Chevy had, the deal
was for Yenko to remove the Winters logo's.

I wonder if you may have the one & only ZL-1 block like this.

That´s not the only one ! Here is a pic of my friend Hans´ NOS Yenko-block with the Winters-logo.
I´m not an expert on these blocks, but I haven´t heard that story before. I believe Yenko bought the tools to make the ZL1-blocks, then changed them to make the blocks more durable. If Winters made these blocks, and they did, why not have the Winters-logo on them ?

Is the Winters mark on the Yenko blocks w/ 'YENKO' cast into the LF....like the one Barnhardt runs in his car, not the style like Anders has w/ the Yenko Logo? .

I recall reading that GM forced that issue of removing the
Winters logo for liability reasons. It was many years ago
that I read this, but I do remember.........

Now I can safely say that this is the first ZL-1 block
I've seen with the Winters logo in that position......
