NHRA Tech is telling racers the cold air hood is no longer allowed on 350/255's from what I was told.

They are being rquired to change hoods....

I bought a cold air hood new from GM and raced with it on my SS/JA Camaro in 1980...350/255.....

Almost every '69 Camaro had them on there. I have no idea why after 30+ years they are no longer allowed.

I would have to guess that they were never produced with that hood on assembly line cars with lower HP engines.

I can't recall seeing the cold air hood on almost any street car....other than a Z/28...

Jerry Macneish would likely know the answer about what exactly was and was not built or available....
