    Manufacturer's Part Number:

    Mopar Performance phased out the very popular 360 Magnum Crate (380 HP) engine several years ago. These engines were designed for use in muscle cars that originally came with a small block V8 engine. You can build a similar engine using this kit to convert a "used" 1993-'03 5.9L Magnum production engine. This kit provides the parts needed to convert a Dodge/Jeep 1993-'03 5.9L Magnum fuel injected engine for use with a carburetor & mechanical fuel pump. This is an economical way to utilize a later model 5.9L Magnum engine in your muscle car, street rod, or other older vehicle that uses a carburetor & mechanical fuel pump. The camshaft, intake manifold, carburetor & distributor are not included with this kit since there are many options to choose from for these parts, and the customer must match these parts to their application.

    Late Model 1993-'03 5.9L Mopar Magnum engines have a lot of advantages over the previous 1971-'86 360 engines and can be converted for use in older vehicles for use with a carburetor and mechanical fuel pump. The 5.9L engine has a hydraulic roller camshaft, higher compression ratio, smaller closed combustion chamber, lighter pistons, lighter valves, and higher cylinder head airflow vs older 360 engines. These engines also have the same motor mounts, bell-housing bolt pattern, and exhaust bolt pattern as the older style 318/340/360 small block Mopar engines.

    Strip down the "used" 5.9L engine to the Long Block & replace the parts with the following:

  • Timing Cover 312-P5249930AB - Allows Use of Mech. Fuel Pump & Early Water Pump
  • Water Pump 312-P5249558 - Allows Use of V-Belt Drive
  • Damper 428-80012 (w/ bolt-on weight #91013) - Proper Ext. Balance & Fits V-Belt Pulleys
  • Fuel Pump eccentric 312-P4120484 - Fits Long Snout Cams (Adapter Required w/ Standard Hyd. Roller Cams)
  • The Intake Manifold Gasket & Hardware Kit 326-615-310
  • Billet Water Neck 555-53251

    Choose a cam that best suits your application (Long Snout Hyd. Roller Cam 249-20-618-9, 249-20-612-9, or 249-20-614-9 - for use with fuel pump eccentric). Top off the engine with an intake that fits the Magnum heads (350-7577 or 312-P5007380AB). Use an external balanced 5.9L flywheel (312-P5249842) or flex plate (130-10242) since this engine is externally balanced. Use a center sump oil pan for most muscle cars (555-50272 & pickup 312-5249563) and rear sump for most trucks. Use an early style ignition kit 555-40500K.

    Note: These parts do not fit or work in a production application (i.e. vehicles that came with a 5.9L engine from the factory - 1993 & up Dodge Trucks and Jeeps). These parts are for use w/ engines that use a carburetor only.

  • Will this kit work on a 5.2 as well

    Asked by: JoeM73
    No, this is only designed to be used with the 5.9L engine.
