Earliest April 3970010 Casting Dates

[Daytona Z]

Found another 010 block that appears to have been cast one day earlier than mine. Anyone seen an earlier 3070010 block than this?

It's been a while since I have seen my original 010 block. It is at my engine builder since he left New York for South Carolina almost 20 years ago! Long story! GreenNV, is there a vin on the side of this block? As I remember, my assembly date is V0424DZ. Vin clearly stamped on the side of the block.

Pic is hard to see. Is it D 15 9 ?

Typo fixed...

My DZ block was a 0421 but the previous casting # block. Must have mixed in on that day.

Yes it is D159. I am working to buy this block from the current owner and I am also checking on the VIN being determined.

Standard bore and in storage for 34 years.

Yup...definitely from the transition period where blocks were switched over from 618 castings to 010 blocks. Here's a 618 block cast one day earlier and stamped V0418DZ. The 010 block above is the earliest date I have seen. I'll post the VIN if we can read it.

Green, you may ant to get in touch with Bryan302 on this site. He has an extensive database of 05A Z's.

[Daytona Z]

Thanks

Bryan and I have communicated many times regarding this block and others. Great guy and enjoy talking with him. 

[x77-69z28]

Yes he is! Let me know if you find a vin on that block. Some were really rd to read. Mine is clear as day.
