1970 Engine?

[KAL7467]

great thread guys I learned a lot found out that mine is l24 013529 and matches my VIN HLS30 10068 on the strut tower stamp...this makes me happy since for some reason I thought it may have been Frankensteined since the valve cover is not one of the earlier ones that the OP mentioned with ohc 2400 on it

More data to use in next update:

1970 240Z 901 white / blue int, VIN HLS30-03435, matching engine L24 006302, E31 0321A, E31 Head, NISSAN 2400 OHC cover, build 4/70.

It appears that block is 1970 Mar 21 A (????)

See Post #27 - Kats expressed an interest in the engine block casting codes. That is how the list I Posted got started.

Kats shows a picture of the block casting codes - and that seems to be the number you are missing.

Hi Carl,

Thank you for "recap" , that is very useful.

Here is mine:

L24 03199 E31 01/70 VIN HLS30-01366 9628A

Does this date code translate to June 28 1969?

[Mike B]

9628A

Does this date code translate to June 28 1969?

It would appear so. That's interesting.

[kats]

Yes, it is interesting ,Johnny'O your 240Z would have a very old block , assembled late 1969.

Who has "9618@" , 18th Jun 1969 is my birthday.I want to see it.

[JohnnyO]

Yes, after sifting through this thread I was surprised to see that early of a block date also.

My block serial number is also low compared to others that were "built" in 01/70. Maybe mine was pulled off the line for one reason or another.

[JohnnyO]

I've dropped this info into a spreadsheet for anyone interested. I was thinking that maybe we could add it as a tab to MikeW's online spreadsheet.
