How do I tell if I have an s/w1 or s/w2 whats the difference

SW1 is a single cam engine. SW2 is a dual cam engine. Look at your engine. If the spark plug wires lead to the middle of the valve cover, it's a dual cam engine. If the plug wires go to plugs on the front side of the engine near the exhaust manifold, it's a single cam engine.
