The cylinders are then diamond honed to an extremely tight tolerance to match the piston diameter (within the nearest 0.0001 inch). Following honing, the main bearing bores are line honed to establish a true, straight centerline for the crankshaft.

This precision work involves checking and correcting the balance of the crankshaft, connecting rods, and pistons. The crankshaft is thoroughly checked for run-out and inspected for fatigue before being polished and ground to strict concentricity tolerances (0.0005 or less) to ensure the new bearings receive the best possible surface. Rods are inspected and conditioned, and all bearing clearances checked to ensure proper fitment with the new bearings. Each of the pistons, rings, and pin retainers are meticulously weight matched (to a tolerance of 2 grams or less) prior to crank balancing. Then the entire assembly is dynamically balanced on specialized equipment. This ensures that the engine runs smoothly, minimizing stress on the bearings, and extends the overall life of the components.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eComponents and Parts:\u003c\/h3\u003e\n\u003ch5\u003e\u003cstrong\u003eEngine Core Components\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eCylinder Block\u003c\/li\u003e\n\u003cli\u003eCrankshaft\u003c\/li\u003e\n\u003cli\u003eForged Connecting Rods\u003c\/li\u003e\n\u003cli\u003eStage 2 Camshaft\u003c\/li\u003e\n\u003cli\u003eCoated, Flycut, \u0026amp; Delipped Pistons\u003c\/li\u003e\n\u003cli\u003eNew Harmonic Balancer\u003c\/li\u003e\n\u003cli\u003eBillet Flex Plate (Flywheel is NOT included for manual builds!!!)\u003c\/li\u003e\n\u003cli\u003eMain Bearings\u003c\/li\u003e\n\u003cli\u003eRod Bearings\u003c\/li\u003e\n\u003cli\u003eCam Bearings\u003c\/li\u003e\n\u003cli\u003eMain Bolts\u003c\/li\u003e\n\u003cli\u003eNew Lifters\u003c\/li\u003e\n\u003cli\u003eBillet Freeze Plugs\u003c\/li\u003e\n\u003cli\u003eRear Main Seal\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Choate Performance","offers":[{"title":"Automatic","offer_id":50378041590064,"sku":"CEP73SWL","price":9400.0,"currency_code":"USD","in_stock":true},{"title":"Manual","offer_id":50378043851056,"sku":"CEP73SWLM","price":9400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/2680\/1200\/files\/Attachment-1_5.png?v=1759939598"},{"product_id":"7-3l-1999-2003-powerstroke-full-running-daily-driver-ford-diesel-crate-engine-choate-performance-copy","title":"7.3L 1999-2003 Powerstroke Full Running Workhorse Ford Diesel Crate Engine Choate Performance","description":"\u003ch2\u003e7.3L 1999-2003 Powerstroke Full Running Workhorse Engine\u003c\/h2\u003e\n\u003cp\u003eThe “Workhorse” model is specifically designed for the working man who requires maximum durability and reliability for regular heavy hauling and strenuous towing.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cb id=\"docs-internal-guid-f0c4f4e9-7fff-2817-87c8-2bb457323bf1\"\u003e\u003cspan\u003eKey Features and Fixes\u003c\/span\u003e\u003c\/b\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eUpgrades Over the Daily Driver:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eO-Ringed Heads\u003c\/li\u003e\n\u003cli\u003eBillet Flex Plate\u003c\/li\u003e\n\u003cli\u003eCoated, Fly Cut and Delipped Pistons\u003c\/li\u003e\n\u003cli\u003eStage 2 Cam\u003c\/li\u003e\n\u003cli\u003eChromoly Pushrods\u003c\/li\u003e\n\u003cli\u003eUpgraded Connecting Rods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eCore Performance \u0026amp; Power\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Output Performance:\u003c\/strong\u003e Rated for \u003cstrong\u003e425+ HP\u003c\/strong\u003e capability, delivering significant power over stock for demanding applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully Balanced Rotating Assembly:\u003c\/strong\u003e Precision-balanced components ensure smooth, vibration-free operation and extended bearing life at high RPMs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eReliability \u0026amp; Durability Upgrades\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Cracking Elimination:\u003c\/strong\u003e Upgraded valves and hardened valve seats used to exceed OEM standards.
