Description
- Extend the life of your crankshaft by changing the firing order of your engine.
- The OEM firing order ends with cylinder 3 and begins with cylinders 1 and 2. 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.
- After 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. In moving cylinders 3, 1 and 2 away from each other, we have significantly extended the abuse the crankshaft can withstand.
- Swapping a few pins in the wiring harness will insure the ECM sends the injector signal to the correct cylinder. Wiring diagrams and instructions are included with every purchase.
- Does not require any piston valve pockets.
- Works well from idle past 3800 rpm
- Valve Lash .012/.012
- The camshaft is an integral part of your engine breathing characteristics
- The camshaft lobe profiles need to be carefully matched to the rest of the engine components in order to achieve maximum performance for any given application.
- We have designed profiles to meet many different applications that include dedicated Drag Racing and Sled Pulling
VALVE ADJUSTMENT PROCEDURE
- Rotate the engine and adjust one cylinder at a time.
- When the exhaust valves just begin to open, adjust the intake.
- When the intake valves are just past maximum life, adjust the exhaust
