I believe a lot of stock flat hoods have been changed to cowl hoods.

Only (1 in 24) ,69 Camaros had cowl hoods.  I don't  believe it was often ,that an original  cowl  hood , (Week stamped)  left its original car, and wound up on another.  Most cowl hoods added to cars , were from (over the counter)...A survey would probably show, that most  (Week stamped ) hoods , are close to the build date!...DON

Rat,
NOS is often stamped / marked differently than production parts.

Actually those that do have stamps are usually just like assy line pcs, but the majority of the OEM NOS stuff does not have stamps or markings of anykind. I have found that early replacement parts are usually the ones that have a stamping of some sort on them and is usually not visible once installed. Recent puchases of NOS fenders, hoods, 1/4 panels, and even tailpanels have no markings.  Found one header panel that did have a stamping of 12, but  that is about it. I wish there were stampings on all GM sheetmetal to help identify them as to being OEM. Repro parts with GM stickers are starting to show up more and more at swap meets and on the internet for sale. Unless you know what to look for it will be next to impossible to figure out whether you bought GM or repro parts............RatPack...................

Good conversation on this topic. 

It will be interesting to determine if we can authenticate if the hoods on our cars are original to our cars, similar to date codes on the rear quarter panels, etc.  That is the reason I recommend we generate a list of body build dates vs. hood stamp dates to evaluate trends like we did on gas tanks.  Those with survivor cars can be significant contributors.  However, Kurt does mention a good point that, unlike gas tanks, hoods are easily replaced, so correlation between car and hood could be messy.

Question:  I assume (based on the updated CRG Research Report, “The First-Generation Camaro Assembly Process”), that the cowl induction hoods were stamped and manufactured my Fisher Body then shipped over to the Chevrolet Assembly Plant, with the rest of the front end sheet metal?

Nope. The front end sheet metal forward of the firewall (hood, inner and outer fenders, header panel, fender extensions, front valance panel, radiator support, hood latch support, fender braces, etc.) was manufactured by Chevrolet, and was painted and installed on the Chevrolet side of the plants. The cowl vent grille was supplied by Fisher Body - everything else was from Chevrolet.

Interesting...thanks JohnZ.

I have an pretty original 08C car that was ordered with a cowl hood. The date code on my hood is 26.

[Dave69x33]

BULLITT65,

Thanks for your input.  So far we have:

Car Build date w/Hood Date Code
05A with 18th week - cowl hood, Norwood car
05A with 18th week - cowl hood, assembly plant not stated by kurt s
08C with 26th week - cowl hood, assembly plant not stated by BULLITT65[/li][/list]

[BULLITT65]

I have a Norwood car as well, sorry thought the date gave it away...
no problem Dave...

And the other Kurt S's hood is from Z10, so it's NOR.
