Big Block Smog Tubes Identification 66 67 Corvette 67 Camaro ?
 

Just Picked these up from a collection of NOS parts locally, My guess is 1966 1967 Corvette Big Block but want to confirm I am right ?

Any help on specific model and engines much appreciated.

I'd say through 1970 when they went to a flat style crimp, give or take a few months.
