CUSTOM BUILDS AVAILABLE. CALL US AT (725) 238-2002 TO DISCUSS YOUR PROJECT NEEDS BEFORE PLACING ORDER. PPE has taken our advanced engineering knowledge and created Duramax diesel engine builds that are tailor-fit to your specific needs. Now you choose how “built” your engine will be. Short-block options begin with original GM parts in Stage 1 and are able to hold more horsepower and torque as the stages increase. If you want a long block engine, you have a choice in cylinder heads, which provide an increase in horsepower and torque as the stage increases. Create the engine of your dreams. There is sure to be the right combination of build for anyone: from street to strip, heavy-hauling to sled pulling. Each engine is built with PPE Cast Pistons. Each engine block and crank are managed before the build. The block is decked, honed and the mains are machined for straightness. The entire rotating assembly is balanced and blueprinted. All our engines come with heavy-duty rods and thrust bearings. Available with compression ratio ranging from 15:1 - 16.5:1 (These parts are an optional upgrade: heavy-duty crankshaft, PPE Xtreme Damper, and ARP main studs are available options.) Level 2 adds Carrillo Rods, ARP main studs, and PPE Extreme Damper to the build sheet listed above. NOTE: Custom builds available. Call us at (725) 238-2002 to discuss your project needs before placing order. *Engine does not include - Flex Plate, Water Pump, Coolant Tube, or Oil Cooler
