Rather than mixing a cam with whatever springs are already in the head, this combines the camshaft with springs that control the valvetrain to 4,500 RPM and 80 lbs of boost, pushrods rated well beyond 2,000 HP, and 1.45 inch tappets for more lobe contact area.\u003c\/p\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e178\/208 camshaft\u003c\/li\u003e\n\u003cli\u003eExtreme duty pushrods, rated from OEM power to over 2,000 HP\u003c\/li\u003e\n\u003cli\u003e155 lb valve springs\u003c\/li\u003e\n\u003cli\u003eRetainers and locks\u003c\/li\u003e\n\u003cli\u003eLifters and tappets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eQuickest spool and widest RPM band of the Hamilton cam range\u003c\/li\u003e\n\u003cli\u003eOriginally developed for work trucks needing low-RPM torque; also helps spool large single turbochargers\u003c\/li\u003e\n\u003cli\u003eReported benefits include improved fuel economy, lower EGT and better power retention at altitude\u003c\/li\u003e\n\u003cli\u003e49-state EPA compliant\u003c\/li\u003e\n\u003cli\u003eHamilton dyno results on a 6.7L with a single S400: 1,100 HP stock head, 1,250 HP stock head with larger valves, 1,588 HP at 4,500 RPM with a ported head\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e1989-1998 Dodge Ram 5.9L Cummins 12-valve\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVerify piston-to-valve clearance during assembly\u003c\/li\u003e\n\u003cli\u003eIf minimum clearance is not met, run an oversized head gasket or cut valve reliefs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eBreak-In and Oil\u003c\/h4\u003e\u003cp\u003eApply quality assembly lube to the camshaft and tappet faces, prime the oil pump and filter on a fresh build, and crank with fuel disconnected until oil pressure is confirmed.
