Does anyone have an idea of what a WS 1965 Engine is worth in good condition? What about a WS 1965 Engine? No Carbs just engine and exhaust manifolds. I have a 1965 GTO that originally had a WS engine but as many did the engine was done by late 1967 and was replaced. Thinking about putting in a period correct WS but don't want to pay too much for it.
