A rear Supercar oddity up for auction

Hey everybody!

Here's a good one. Check out eBay Item number: 8044553424

This is a rough casting of an original ZL-1 block. And,
when I say rough, I mean rough. It comes complete with the
Winter's foundry logo and '052 part number. As far as
useable stuff goes, that's about it.

This block is not milled in any way ( deck, mains, bores,
lifters, oil passages, water jackets on the deck, internal
threads on the decks, timing cover, oil pan rails, etc.).
I'm sure there are other things that need to be done as well
to this block.

It's a nice conversation piece for the ZL-1 crowd, but how
useable is it in the real world?

So the question is really this. Could any shop actually be
able to perform all of the milling required on this block?
The oil passages alone need to be gun-drilled and that can
be expensive. I looked into this once to convert a 2-bolt
main block into a 4-bolt main block ( correct casting date
& casting number ). I bet the milling costs would be
astronomical to say the least assuming that it could be
done dimensionally correct. You only get one chance with
that much work.......

So, assuming that all the planets were properly alligned and
you were in-good the the big guy upstairs, could this block
be machined properly today? All of the original setup
tooling at GM for Mark IV blocks is probably gone by now.

Actually, where were these aluminum 427 blocks machined back
in the day? Was that work done in Tonowanda as well?

Just wondering what others think about it.

Steve

It would make a real nice coffee table.

my guess is that it did not pass inspection to be machined. im sure you could get a rough block as you can now and set your own crank centerline and deck ht for a custom stroke but this thing is really rough. great find though.
