Tom,
You will need to follow up on this and confirm but...
Your intake casting # should be 3866948 if it came with a holley and the engine sufix should be IVH if it came with the turbo 400.
The tag stuff should be
12B Dec 2nd week build
844 - Blue int
F 1 marina blue with white top
W2ZS 5Y
W Tinted windshield
2 - Group 2 options Z should be Turbo 400
S rear antenna
5 - Group 5 options y deluxe seat belt
the option codes are not an exact science so you need to do more research
Sounds like a nice color combo car
