"Numbers matching" is really more important on the pre 1972 Chevrolet cars. Starting in 1972 the engine was coded into the VIN for Chevrolet cars. Prior to that the VIN only told you if it had a V8 originally or not. Some VIN's on Chevelle's are SS specific but not for Camaros. So for a 67-71 Camaro it's pretty important to have the original motor and transmission with the partial VIN stamped into it. It's not that big of a deal for the low performance motors like the 327 2 bbl and 307 motors. But for SS, Z28, COPO 427 cars it adds a lot of value. The 67's had some of the engine options coded into the firewall trim tag and some of the 69's also show the SS or Z28 option on the trim tag and some of the 70-74 show them as well. But there are a lot of fake, transferred and reproduction tags popping up so you can't trust the tag alone to prove a car is an SS or Z28. My 69 Z28 has the Protect-o-plate which is the warranty card plate showing the engine, trans, rear, radio, brake options. My motor and trans have the partial VIN stamped in them proving they are the originals and I also have the broadcast sheet that was glued on the gas tank showing most of the options.
