COPO 9010 Carburetor

[YENKO DEUCE REGISTRY]

Stan;
To our knowledge the Holleys installed on the a/t Deuces were 4490's. I have not seen any 4800's, nor any 4454's. I don't know what 'NB-2' is. I have a Yenko Deuce article written by Alan Colvin in 1996 where he lists a 4556 as the carb for the a/t LT1's, but I believe that is a California carb.

Here is what NHRA shows:

Holl 4489-1A/SM, 4454-1A/AUTO, 4555-A/SM 4490-A/AUTO, 1686x1686/1375x1437

This takes in the Camaro and the Corvette, as well as the Nova, but is this info close to being correct?

Now, this is a little off topic, but what carb would have came on a '66 L-79 Nova?

Thanks for the information guys!

I said NB-2, but meant NA-9 (my mind is starting to go - at least I got the "N" right). That was the California emissions option I've seen on a few 1970 LT-1 Corvettes. Basically carbon canister, vent line, carb shield, etc.

In any case, thanks again!

Regards,

Stan

I just cleaned up what the NHRA had listed a little bit:

Did the Nova, Z-28, and Corvette supposedly use the same carb?

To my knowledge the Z28's and Corvette's used different carbs, and the Novas are equivalent to the Z's.

So, the Z/28 (and Nova) used a different carb than the Corvette. So which carb(s) above is designated for which car? Were the Novas and the Z/28s engine components stamped the same? Do they use the same part numbers on the entire LT-1? (eg. could you tell a '70 Z/28 engine from a '70 COPO Nova engine?)
