Wow, Looks good. Never say never on the heads.

I'm not an expert but I don't like it.

the W matches all Willow Run BB Nova VINs that i can find that are posted online..

august 1st cast date...thats early...lol..if the stamp is right..it was machined 7 days later...

[scuncio]

I believe you on the W...like I said I'm no expert.

[marxjunk]

i'm with ya..the W was weird to me too..ya aint no spring chicken ya been around, i value your opinion

[BLACKLS5]

FWIW, It's not the "W" that bothers me.

[marxjunk]

Black, whats the concern? id like to hear all opinions...open communication here..if its not legit..i want to know...i value your opinion

if you dont want to be specific..is it the engine code or VIN? i am by no means an expert..i am an observer...or PM me..i get it

Would a real early car have a VIN derivative of 10W181xxx?
I am more versed in Camaro engine stampings but I dont like the "broach marks".
Looks like they were made up by someone using coarse grit sandpaper.

Great question Jonesy, but I became aware of these type oddities/ discrepancies when this similar engine came up for sale on eBay. http://www.camaros.org/forum/index.php?topic=14633.0
This may explain how a late vin can be assigned to and early assembled engine

Not real crazy about broach lines either.

The 1970 production of the Nova started with VIN 100001...so this VIN would represent the number 81,000 car in the production sequence. The assembly date on the engine is 'early'...based on my assessment. Eg; our 1970 4 spd L78 has a cowl tag date of 12C...engine assembled 11/25...about a month prior to the build. Our VIN is 210xxx, so it is later than this unit by approx. 30,000 cars. We would need some other reference points from fall of 69 Novas to narrow down an exact time frame, but it could be done with fairly good accuracy.

It would be reasonable to expect that the 854 blocks were cast and the initial supply of engines assembled prior to the 70 model year really taking off. Also, the early date of the block could be perceived to support the idea that there were some early production aluminum head motors [like the Chevelle] and then the option was cancelled [img]<<GRAEMLIN_URL>>/dunno.gif[/img]

Someone suggested running an NCRS or Canadian docs on the VIN...that would really help narrow down the ship date and see how that ties into the other facts...provided the data is a available.

The L89 Nova may be the 'Bigfoot' of the car hobby...clues occasionally surface and folks get excited. Having an actual block to examine is certainly a plus...I'm sure there are enough experts here that can confirm if the broach marks/stampings are legit. I have additional L78 examples that can be used for comparison if needed.

Stay tuned..
