1994-2003 7.3L CNC Fabrication Stage 2 Complete Powerstroke Engine PN: 421029
Unleash the true potential of your diesel truck with the 1994.5 through 2003 7.3L CNC Fabrication Stage 2 complete engine! Rated for 600 horsepower, it is built for both passionate enthusiasts and those who require a reliable workhorse, this engine honors the storied legacy of the legendary 7.3L Powerstroke platform.
Experience an immediate boost in driving confidence with consistent output and unmatched reliability at your fingertips. Whether you're breathing new life into a classic daily driver, towing heavy loads, or gearing up for more demanding challenges, this stage 2 engine is your ticket to enhanced performance and efficiency. We use the same build quality in the engines that we drag race our trucks in.
Each engine is machined and assembled in-house to the same standards we use on our competition engines. Features ARP head studs, main studs, and rod bolt, along with our CNC Fabrication stage 2 cylinder heads that are O-ringed, have Inconel valves to handle extreme EGT's, and our beehive valve springs to handle the high boost. The block is torque-plate bored and honed and the main bores are line honed, so the internal geometry is correct from the start. The common 7.3L weak points are addressed with proven upgrades: ARP head studs, a TIG-welded cam gear and piston coolers, and Manton chromoly pushrods.
