DZ block

I have a DZ block for sale on the local Craigslist. I had a guy come to look at it. He is quite knowledgeable about '69 Camaros. That is without a doubt his favorite year. Anyway, he said that every '69 Z-28 with the DZ block, that he has ever seen, had the 1/4 inch plug in the front above, to the left, of the water pump. He doesn't know why it is there, just has it. I don't know, but is that carved in stone? Thoughts on this. Thanks, Roger

Re: DZ block

Yes the square oil gallery plug is a feature of the machining process at Flint V8; Tonawanda-machined small blocks don't have that.

Thanks for reply and the article reference. Very useful information. It appears the block I have may not be a real DZ block, as it does not have the oil galley plug? Or is it? Oh well, not the end of the world.

Re: DZ block

If you can, please post a clear picture of the pad stamp, and also confirm the block casting number and date.

Re: DZ block

I am not a paid subscriber, so I can't post anymore pics. Look at my classified that I had on here, they should be on there. Ad was: 1968 Z28 project for sale. Every reply I got on here, from what they could see with pictures, was a good stamp. Thanks,

Here's the ad (with pics)...https://quadcities.craigslist.org/pt...040938271.html

Interesting, Roger ! I'm well aware of the square plug used on Flint engines. The pad stamp looked good to me, but could be wrong. Jonesy seemed to think it was ok too...

Re: DZ block

I have seen one DZ block that I was pretty certain was an original stamping without the square plug. Jonesy and Kurt both thought it was good as well.

It was a March block.

Re: DZ block

Thanks a lot you guys for your input on this block. I, myself have been doing as much research as I can come up with to make an honest decision myself. I certainly don't want to try to sell this as an original DZ block when in fact it isn't. The bad part is, the guy I got it from, 6 years ago, has passed away, so I can't pick his brain as to the history of it. He was himself a very honest, good guy. Thanks again,
Roger

Re: DZ block

Thats a total legit original stamping and we found the partial VIN too and that matches the time frame of that stamping. 19N631227. V0402DZ.
I cant see a pic of the area with the 1/4" plug. I know its not typical for Flint engine blocks to not have this, but I am confident that this is the original stamping and I would think KurtS would concur.

Re: DZ block

Thanks, Jonesy: I appreciate you looking at this again. I at least still feel okay saying that it is a DZ block. Thanks, Roger
