    AAM Competition 370Z & G37 Stage 4 4.07L to 4.3L Short Block Engine Package

    The AAM Competition Stage 4 VQ37 Shortblock is the ultimate engine block setup for those seeking maximum power output.  This 4.07L to 4.3L stroked and sleeved motor is ready for 1,000+ whp (with optional proprietary block strengthening).

    The added displacement of the stroker kit greatly increases low-end and midrange power.  On boosted application expect the turbochargers to spool up 300 to 600rpm sooner than a comparably setup non-stroker engine.

    The AAM Competition Stage 4 VQ37 Longblock comes with a full one year warranty against machining defects.
