COPO 9010 Carburetor

[Chevy454]

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,

On my car, the carb is 3972121. List 4555.

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?)

Rob;
I believe the 4489 and 4454 carbs were specific to the corvette, but were allowed to be run on the Z28's and vice versa for NHRA tech. purposes.

The only way to tell if a particular LT1 that is coded as a CTB (4speed) or CTC (auto) came from a COPO Nova is if a Nova VIN is stamped on the cylinder pad.
