[mockingbird812]

Eddie M is looking for some feedback on this stamp. Thanks!

Is that a D in the partial vin?

Bad in my opinion.

The partial VIN doesn't make any sense to me. What is "D" for an assembly plant? Van Nuys was L and Norwood was N. The sequence number is way out also. seems weird the broach marks end as it goes under the head, doesn't it?

[enio45]

Yes looks like a D

Im not a 70's expert on this stuff - so appreciate the feedback.....

agree with the broach mark comment - seems weird to me too

[x77-69z28]

Eddie, I’m no expert on stamps, but Camaros were only built in Norwood which would be an N in the vin, or Van Nuys which would be an L. Sequentially, I’m pretty sure they started at 500000. Therefore, I don’t like it!

Is it a whole car? Or just the engine?

[enio45]

whole car - but i don't have the VIN currently - that would tell about the vin stamp for sure

My old 1100 mile Z for comparison

Did they go back to the vin on the pad in 70 or just on Los Angeles cars?

[BCreekDave]

Just LA. It was I've read a GMAD vs. Fisher Body thing. When Norwood went GMAD in 72, they moved to the pad like LA.

[Steve Shauger]

Doesn't resemble original stamps in my database

Thats correct.

I had an original 70z engine and the VIN stamping was down by the filter. NOR car stamped V0518CTB.
This stamping above has some issues. Isnt D for Doraville?? Plant that made the big cars. Definately is not a Camaro VIN.

Whats the casting number on the back of the engine?

[Mr70]

D was indeed used for Doraville,but that CTB code was used for a 1972 Impala series with a 240HP/402cid.

[Jonesy]

Agreed

But in 1970 it was a 350 LT1 4-spd

[Steve Shauger]

OK I will clarify the stamping. It is completely incorrect from fonts, codes & broach marks.

[rszmjt]

Another heavily belt sanded deck. Not even close to original, like noted.

[enio45]

ok thanks guys - appreciate the info and insight

there are some very obvious signs here

[firstgenaddict]

Doesn't this area appear to show a lack of machining as though it were not level with the rest of the block?

Also agree the broach marks nor the assembly stamp are not at all typical.

[Mr.Nickey Nova]

Stamps look a little deep to me. I would say that is a restamped block...

[ronzz572]

Just curious. What is the block cast date? Does it align with the assembly date? Nothing makes sense with the vin and the stamp. Surely a restamped block as I see it and agree with others posted hear earlier. 1970 CTB blocks only have 3 partial vin car line plant uses. W for Willow run for 1970 nova's yenko deuce. L for Vannuys 70 z28 stamped on front pad. N for Norwood 70 z28 stamped on block near oil filter. Not sure where the deuce was stamped.

[mockingbird812]

Deuce partial VIN stamp is located top-side of block.
