Okay I *think* I'm getting better at this but I still don't quite get all the codes yet, and I want to make sure this car is what I think it says:

Anyway here is the trim tag:

11B (2nd week November?) T (?)
67-12637 (1967, Deluxe interior Coupe) NOR (Norwood) 33376 (Body number)
779-Z (Deluxe Turquoise with Strato Buckets) L-L (Tahoe Turquoise upper/lower)
WL (tinted windshield/fold down seat) 2MG (Powerglide with console) 3SDL
Interior Decor Group, underdash lights, Rally Sport)
5B(large rear bumper guards)

This all seems to make sense...it's a V8 car so, it'd be a 327/powerglide right?

Vin is:124377N132968 which hopefully lines up...

So, it should be a 1967 Turquoise/Turquoise 327/'glide Rally Sport, right?

1 = Chevrolet
2 = Camaro
4 = 8-cylinder engine
37 = coupe body
7 = 1967 model year

Decode for body number: 033376

11B = Built the Second week of November.
67-12637 = Custom Interior Coupe.
NOR = Built in Norwood Ohio.
779 = Custom Turquoise Bucket Seats.
Z = (A50) Strato Bucket Seats (without headrests).
L-L = Car Color is Tahoe Turquoise
T = Interior paint is Turquoise
Options:
1W = (A02) Tinted W/S only
1L = (A67) Fold-down rear seat
2M = (M35) Powerglide Transmission
2G = (D55) Console front compartment
3S = (Z23) Interior Decor group
3D = (U29) Courtesy Lamp
3L = (Z22) Rally Sport Package
5B = (V32) Rear Large Bumper Guards
------------------
Looks good to me
November 1966 126721--141482

VIN looks good for an 11B car. The only thing your decode missed is that the "T" stands for turquoise interior paint.

Yes, it would be one of the 327s. Only the size of an original fuel line would tell you which of the two 327s it came with.
