Welcome to CHR!
The exhaust sounds like it's fairly open (Flowmaster 40 or similar with headers?) and some work has been done internally which may have included a cam with a bit longer cycle/duration. Do you know the cfm on the carb? 600-650 is fine, anything bigger will definitely consume more fuel and probably not contribute to performance. When you say you ran the numbers - are you talking the casting number of the block or the numbers stamped on the pad on the passenger side of the block?
12.5mpg overall may not be that bad - considering the weight of the vehicle and the rear-end ratio is fairly tall to get things moving. Have you done a freeway drive, say 200-300 miles at 55-70mph? My insides tell me you'll see a dramatic improvement in mpg (say 16-20mpg).
My two cents,
Glenn
I'm trying to uploads pics but they won't upload. It is a performer quadrajet so it's not that great. I think about 600cfm.
It has exhaust manifolds and dual pipes with 16" glasspacks. I will keep trying to upload pics.
Some pics for you

So that's it. Why I'm asking this question is because people ask what cam it has? I dont know, some people told me it sounded like a 30-30 cam. Don't know what that is? So I thought it was stock but apparently it was changed with the motor rebuild.
Seems like someone else mentioned that they had to hit a ten post threshold before they could post pictures, something about keeping the spammers out?Quote:

A 30-30 cam is what Chevrolet used in 375hp Corvettes in 1964 and so named since the valve lash is 30 for the intake valve and 30 for the exhaust valve. It's also a solid lifter cam which will be somewhat noisy and have a definite lope.
