Description

This is what we call our "Tow/Mild Street Build" Longblock which is a rated for mild upgrades like a small upgraded turbo/injector combo packages for more efficient towing use,  we go through our Duramax Longblocks and get rid of all the factory weak points they are known for and are common issues.  All of our Duramax Longblocks come standard with Mahle/Dualoy LB7 OE Style Pistons, we get rid of the 5mm dowel pins on the crank and cam by machining a keyway into these areas on the crankshaft and camshaft to get rid of the dowel pin shearing issues, we use the Wagler Competition Oil Pumps which are pinned and shimmed to increase oil pressure.  All of our longblocks come with ARP Head Studs as a standard option.  Our "Tow / Mild Street Build" Longblocks include a Callies Durastar Forged Crank, ARP Rod Bolts, ARP Main Studs, and SBI Performance Valve Springs that retain factory keepers and retainers. If you do not see options or build specs on our listings of how you want your longblock built or your not sure of how you need your motor built please contact us via email for the fastest response and we can quote out how you would like it built, our email is sales@xcaliburdiesel.com

 While this setup is a solid and strong setup keep in mind your still using stock rods which have limitations, a general estimate hp on LBZ Rods are 600hp-650hp at the flywheel,  depends on tuning, fuel, and turbo setups.  If you feel you are or will be over this upgrade to a Forged Rod.  Forged Rods are good for 1000hp builds but this doesn't mean the bottom end will handle it as once you get to the 750hp mark you need to add Billet Main Caps.  If you are at this HP please email us for a quote for a build to suit your needs.
