    AAM Competition VQ37 370Z & G37 Stage 3 4.0L Short Block Engine Package

    The AAM Competition VQ37 STG III 4.0L Short Block is intended for those looking to push the limits of their boosted application.  Utilizing a 4.0L Stroker Kit, the AAM Competition STG III Short Block is capable of supporting 850+whp  while generating increased low-end and midrange power from the stroker kit's larger engine displacement. On boosted applications expect the turbochargers to spool up and deliver more power 400-600rpm sooner than a comparable setup non-stoker engine.

    The AAM Competition VQ37 Stage 3 Longblock Engine Package comes with a full one year warranty against machining defects.

    • Massive increase in torque
    • Capable of supporting 850+whp
