What do I have in this 78 el camino?

I have been told that this is a SS Model, some people say no. It has a 350 engine ( Which I was told it did not come with from factory, but it has it on a model tag on the core support ) So i can send pictures to whom can help me @ tomacarlton@yahoo.com Thanks Toma

78's did indeed come with a 350. It was very under powered at around 160 horsepower. Look at your cowl tag ( just above your wiper motor.) If it has a "Z 15" on it, it is an SS. The SS was nothing more than a cosmetic package by then. There were no power or suspension modifications to go along with it.
