It has over 138,000 miles. An individual coil for each spark plug delivers maximum voltage and consistent spark density, with no variation between cylinders.

The 350 vortec often uses a high tourqe mini starter. Long story short I ended up rebuilding this engine this summer. All engines have cast iron blocks and cylinder heads. The system uses oil pressure, controlled by the powertrain control module, to deactivate the lifters on selected cylinders, closing the valves for those cylinders.
I don't know anywhere else to look besides watching Ebay. The camshaft specifications for the 4. Shouldn't 10W30 or 10W40 be used? The 229 cu in 3. That helps ensure proper sealing for the life of the engine and reduces the chance of gasket failure. Emissions are also reduced, particularly during cold starts, when hydrocarbon emissions are cut by about 25 percent.
However, the connecting rods were still the same 5. The engine power is not usually a limiting… Okay first of all there is a few things you need to know about these type of engines.

It is a dual-equal cam phasing system that adjusts camshaft timing at the same rate for both intake and exhaust valves. Society of Automotive Engineers, Inc. Although package size is usually not a concern with full-size pickups, lighter weight and lower friction can both contribute to improved efficiency. The engines also feature a new cylinder-head design and a new, sculpted piston to optimize the mixing of air and fuel in the engine and the burning of the mixture to create power.
