Cowl Hood

[ron morehead]

I have spoken to old sales persons that sold these cars in 69 1 guy particular swears he sold those hoods on everything except to 2 bbl cars never made an air cleaner setup for that carb/ hood set up. What I don’t understand is there is an option for just hood with no mention that cannot be on s 255 just looking for Chevrolet info seems like a lot of hearsay no difinitive evidence please some prove me wrong so I can plan properly

The cowl hood was an option on Z-28, SS, Pace Cars and standard on COPO's the 350/255 was not available in any of those combinations

Ron, this ship has sailed. This was NOT a knee jerk reaction from NHRA. You could contact Jerry McNeish, he is highly regarded as an expert on 69 Camaros. NHRA may have consulted him before they made their decision ?

Ron...Check out : Camaro.org (Camaro Research Group)
You will find all the information you need, the site is extremely informative. The Cowl Hood was the ZL2 option. All the COPO's and ZL1 cars came with them, as Standard equipment. Those cars all had Holley's and a sealed to hood air filter assembly. I bought a 69 SS 350/255 , TH350 column shift and 10 bolt. It Originally came with the porthole hood inserts.
I am currently building a Hugger Orange ZL1 Clone out of it (beyond Bucket List). Hope this helps...Maurice.

Ron, look up the Camaro Research Group (CRG). Yes there is actually one. If you join from what I understand they can get you that answer. Barry ----- Maurice you beat me by a couple of minutes

I recall this question being discussed on this site a few years ago ... lots of debate and info was offered. In the end however if we want to play in the NHRA sandbox ... well you know the rest LOL.

Anyway year ago when I raced a 350/255 my brother and I did the hood swap at the track to see if it was worth anything. With the cowl hood and air cleaner base we felt at the most .04. With the flat hood now that you can run an after market air cleaner base there is no advantage. BP

Maurice, Barry
Thank you for that info I have a fiend looking to redo a 69 convertible (like the one I raced for years with the cowl hood) that came with the 255. He says that it came with the Cowl Hood and I could not find anywhere that says he is either right or wrong, that is why I am asking. I have not seen anything from GM that states that you could not either get or was not available anywhere I have looked. Thanks again

Ron... Hurdles, Where would we be without them. I built a 1968 Nova Super Stocker, with a 1970 402-375. I have the taillight, marker light and instrument cluster issue. I wish I could find documents that read "It's a 68-72 Nova, forget about it".
I don't know how people would respond. Any opinions on an old topic? MB.

The reason that you cannot use a cowl hood on a 350/255 combination is that the 350/255 engine option was cancelled, during the model year, before the cowl hood was released.
The two never existed at the same time on the Camaro RPO list so the two options were never available together on a car.
It is as simple as that.
