No, camaro came from the factory with Z28 stripes except the Z28's and the pace cars. But since it's been repainted someone could have added anything they wanted. There is no color exclusive to an SS car.
The heater dore is from a small block car, if it is in near the engine. Big blocks had heater tubes out near the hood hinge.
SS's will have either an L48 350/300HP or any of the 4 available big blocks. Norwood Big blocks made after 12/15/68 (or so) will be coded with an X22 or X66 code on the trim tag. LA built cars do not have X codes.
SS's required the following:
1. Front disc brakes
2. Multileaf rear springs
3. 12 bolt rear axle
4. dual exhaust (check for a 2" by 5" metal plate welded on the outside of the drivers side rear frame rail just behind the shock- this is the original support bracket for the dual exhaust on coupes)
SS's came stock with the SS hood, which used a different spring than a stock or ZL2 cowl induction hood.
look here for a picture of the springs:
An L78/L89 would have a single 3/8" fuel line on the passenger side frame.
There should be a rear brake balancing valve mounted on the drivers side front frame under the drivers seat.
