The result is a 3-1-2 hit to the crankshaft. Duramax cranks have a tendency to break right behind the first rod throw at the intersection of the second main journal, right where the 3-1-2 hit would stress the crankshaft the most. Coincidence? We think not.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eAfter carefully researching the different firing orders available to a V-8 engine, SoCal Diesel was the first to implement this \"Alternative Firing Order\" camshaft for the Duramax engine.
