Hello,
Looking at the pictures, I am pretty sure this is a first generation SS from the early 1990's DEFINETLY NOT a LS or LS conversion.

Since it has the original Nelson backplate mount, it's possible it's even an ABC engine rather than AAC, and may be of the "square port" variety. You can tell ABC or AAC simply by looking at the top of the liner between the head and case and seeing what the liner flange is made of. You can tell if it's a square or arch port by taking the muffler off. If the top of the exhaust port is straight, rather than arched, it's from the very first generation engines.
