  • These engines are designed to replace the tired 5.0L in your Fox body. Available in either a hypereutectic piston and cast iron cylinder head or forged piston and aluminum cylinder head version.

  • Does it come with injectors and if not what size is recommended?

    Asked by: Aaron k
    Injectors would not be supplied with this engine but we would recommend that the stock ECU be tuned/chipped and 24LB injectors. If the stock ECU calibration and 19LB injectors are used, it could result in engine failure.

    Can this engine support low boost?

    Asked by: 50 Stang
    Yes, it has 9.5:1 compression so it will work with mild boost.

    Can it replace the 5.0 h.o. in my 1989 Lincoln mark vii LSC, direct fit replacement? Or only mustangs?

    Asked by: T biscuit
    This engine is for the Mustang only. It is not compatible with any other model.

    Does this engine come with the upper and lower intake or am I miss reading this discription? And can this be used with a stock ecu? What size injectors are recommended?

    Asked by: Dustin50
    Yes it does come with the intake(upper and lower), BluePrint recommends upgrading injectors to 24lbs and calibrate the ECU. The stock injectors and ECU could cause the engine to run lean and result in engine failure.
