Well the 67 Camaro is going full circle. The fake data plate has been removed and a new reproduction one has been ordered. Thanks to Kurt for having a picture of the original to go from. The stamps on the engine block have been punched flat and a new coat of orange paint will cover it as well. The car will (for now) remain a 396 and will keep the SS emblems even though this was originally a 327 RS car.
Thanks to all for your help on this.
Now for a little update on the details of the car. I have added the proper engine stands and transmission cross member for the big block. Cleaned the engine bay and repainted everything. Replaced the valve covers and air cleaner because of a little rust. New stickers and changed the carburetor to a Holley spreadbore. It runs much better and looks very nice.
