Like all of our other award winning engine packages, our 7.3 engines start with a thorough disassembly and inspection process to qualify all cores to make sure they're up to our standards. After cleaning, blocks are pressure tested to ensure no "pinholes" or "hairline cracks" or other defects make it any further in the process. All bolt holes are carefully cleaned and inspected to ensure no rusted or damaged threads or bolt bosses make it to our customers. Block machine work is performed in our brand new state of the art RMC V40 CNC machine, which completes the blueprint boring, decking and chamfering to reset all of the bore centerlines and head gasket surface back to factory geometry. Blocks are then treated to a CNC torque plate hone in our new Sunnen SV-15 cylinder hone, where cylinder bores are honed within .0001" tolerance, as well as setting proper cylinder surface finish (RK, RVK, RPK, Mr1, Mr2, measured with state of the art Mitotoyo Profilometer) critical for proper piston ring seal, break-in and adequate oil retention and ring rotation for years of reliable service. All blocks are also align honed to ensure the main housing bore is straight and true, with proper bearing clearance.
All KDD rotating assemblies are balanced on our state of the art CWT 5500 balancing machine, to ensure proper balancing for the application, followed by micro-polishing and checked for straightness. Genuine Ford rods are checked for straightness, new pin bushings installed, and optional ARP rod bolts available. Optional USA made forged steel Carillo connecting rods. or Brian Crower forged steel rods.
