AAM Competition 370Z & G37 STGIV 4.07L to 4.3L Stroker Kit Engine Package

The AAM Competition Stage 4 VQ37 Longblock is the ultimate engine 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.

Exclusive Benefits

  • The strongest, best optioned engine package available for the VQ37VHR
  • Capable of supporting 1,000+ whp

Features
