I purchased a 1969 Z/28 about one year ago. I was not too concerned about numbers matching, but I am curious about the block. It is stamped DZ CE with no numbers and have been told this is because it is a crate engine. Can anyone confirm this for me, and if it is a crate engine, would it really be a DZ block? Or has someone re stamped this block?

Doesnt sound legit to me. Should be either CE or DZ with a number following each one. Could be a real CE 302 that someone added the DZ to add a little legitimacy to it. I would consider it non matching numbers.

You Rob! Is that you?? If it is you....

Here is a link to some pictures of that motor as I was rebuilding it...

You may want to move this to the "tag team" section as that is where we typically discuss this type of stuff. Anyway- The "CE" designation was for factory or warranty replacement blocks, and I am pretty sure that it could also mean an over the counter bought engine. The "DZ" stamp tells you it was a 69 Z28 block. You can tell if it is a re-stamp because it won't have the factory broach marks due to decking. Do a search on "CE" and you should find some good stuff.

I can tell you the deck height on that block was .025"- so pretty much guarantee it has never been decked and re-stamped. I used the .018" head gaskets, so you will have a .043" quench height with those JE 10.5:1 pistons.

If this isn't Rob, then disregard the specific comments on the particular engine. Welcome to the forum!
