GM did a lot of option mixing , I used to get in an argument every weekend at a cruz in or car show with my 67 , it is a 327 210 horsepower with a two barrell carb but it has a console with gauge's and factory installed tach , people would argue up and down that because it was a two barrell it COULD NOT have a factory tach , well after more info surfaced come to find out my tach redlines at 5K which is only correct for one engine A 327 210 HORSEPOWER ! I had a 69 chevelle that came from the factory with a 396 375 and a muncie 3 speed ! found the build sheet under the carpet it was coded MC1 muncie 3 speed ! so to have a camaro with a deluxe interior and no console would have been a normal thing ,,
