66 Impala 396 intake and carb?

[COPO 70 RS/Z28]

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
