Jim, I am not trying to tell you what your car was or was not, I am trying to learn more about decoding the tags and styles. The VIN will provide more information such as build plant and body style designation. I've been building decoding databases for 20+ years and NO ONE has a perfect database. The more information that is collected, the better the database.
Go to Geoff's '68 Dealer Album. You will see that according to the Pontiac-published dealer album, Sprints came with 250 cubic inch 4 bbl, flat hood with OHC emblems, and rocker panel emblems. Firebird 350 HO came with high output 350 4 bbl and HO stripe package (which could be deleted). If yours was different, the information would be very valuable.
I can't explain the '67 trim tags. I would certainly like to find out why the car has both designations, such as one of the two codes may be incorrect in the body tag decoders, or the three assembly plants used different codes for different options. The '67 on eBay does not have Sprint badges on the rockers, it does have a 400 hood, VIN matches a V8 car. I'd like to see a broadcast sheet on that one!
