Does the data base contain any records of '69 Z/28's with DZ coded engines bearing the 3970010 casting number? Can you tell me how many incidents there are? It's a strange request I know but it's sort of meant to settle a bet.
thanks

Thanks William. I was aware that it was used for a number of 4" bore applications.
What I'm looking for are actual numbers of 302's that used "010" blocks. A statement has been made that the "010" was only used for 350's and that few, if any, 302's were built using the "010". Empirical data often puts this sort of thing to rest so I was hoping that you guys, as the keepers of the data base, might be able to shed a little empirical light on that subject. I'm not asking for VINs or anything just how many "010" blocked Z's in the data base. A total number of Z's in the data base would be helpful to give an idea of percentage as well.

My CE engine 302 is a 3970010

So's mine but I don't think that helps to refute the statement above - if you take my meaning.
-
I think the majority were built with the 010. April on. There were two other cast numbers prior.
-
Jerry's book (page 19) indicates that the 010 block was used on 69's from April through November, 1969.

JohnZ and L78 Steve: I get your point but the gentleman who made the statement above ( that "010" blocks were only used for 350's) is also asserting that the books that show "010" blocks as possible for 302's are in error and that few, if any, 302s were built (during production) using the "010" block. Frankly I think it's a BS statement. It would seem that pretty much after April of '69 the "010" is GM's go to block for 4" bore small blocks so it would follow that any Z's built after April would most likely have an "010" block. I'm just looking for something to support my position other than the aforementioned books (the content of which he has already discounted).
I know someone is probably asking why I care - well, being right has its merits ;D but really it's a matter of whether or not to let misinformation stand. If it is left to stand then it has the very real possibility of becoming "fact" and we have plenty of misinformation that becomes "fact" in this hobby as it is.

All I can say is all 302's after april 69 were to get 010's. There may have been incidents of the earlier block used after April.

I have a late April Z (04C) that has the 618.

I accept your argument but upon what do you base it? Is it simply a more succinct stating of what I said above or do you have some evidence to support it?
-
My initial query was based upon the assumption that the data base contained the sort of info I'm requesting.
Is my assumption in error?
If my assumption is correct then is there a specific form to be filled out or procedure to be followed in requesting such a search from the data base? If I've breached protocol then, by all means, let me know and will follow the SOP.

My 10E car has a 3970010 block.
I once owned a 1973 El Camino that had a 350 in it with the same block.

The first week of May '69 saw the last of the 618 castings and the first 010s. All 010s from then on.
-
Yup, all later 302's used 010 blocks. So lots...

my 05A car is the 010 block,

I have a 010 CE block, dated 11 69, with series # after it, and on the bottom, by the oil filter location, a date of K0215 . It had a # written on the side of the block in crayon of #3970647. A guy at the dealership told me it was replacement ' 69 Z fitted block, and that 397# was a service replacement # , ordered through the parts department. Sounds like someone turned a bearing, or worse, and had it replaced under warranty.
Looks like CE 9 5XXXX. It is a bare block though, no crank/rods or pistons, and no VIN. And NO, I don't want to sell it.
-
Ok, it has a code of T0218, it was a 8 instead of a 5, and has a K under it, all by the starter flange . So, it has a Tonawanda CE code and date, but a McKinnon foundry cast block, and K by the date also. Anyone seen anything like this? Did Tonawanda have a strike, and they use McKinnon cast blocks for warranty? Just curious. Never seen one like this... ever! It is a 4 bolt bare block.

A "CE" replacement fitted block (block and pistons, no crank or rods) for a 302 wouldn't have come from Tonawanda; they didn't have the domed pistons in stock. Only Flint V-8 had domed pistons, solid-lifter cams, the 1178 crank, and the 2.02/1.60 big-valve head machining station with the intake valve unshrouding cutter in the cylinder head machining line. Tonawanda only built hydraulic-lifter 350's with flat-top pistons and 1.94/1.50 valves.

my 05A z has the 010 block, i havent found anyone with an earlier vin with it.
