Description

The AMS EVO IV/V/VI/VII/VIII/IX 2.3 Stroker Short Block is the ultimate solution for low RPM torque. With an increase in displacement to 2.3 liters, you can expect a 10-15% increase in torque and a 400-500 rpm increase in spool up. Road racers will pull through corners better and drag racers will benefit from boost response after shifts.

We use only the best off the shelf and custom designed AMS spec components. Combine that with the latest in machine and assembly practices and you are assured only the best!

All our engines are hand assembled at AMS using the same care as the engine in our world record holding, 1142 awhp AMS EVO VIII. Every motor is balanced, blueprinted and assembled to AMS’ exacting standards.

Before assembly each block is checked for correct dimensions, cylinder bore, mains, block flatness, etc… to ensure you get the best foundation for your new engine. Every engine we assemble has a build sheet where tolerances, torque specs, and clearances are documented.

An exclusive feature on all AMS EVO short blocks is our Race Balance Shaft Eliminator Kit. We do not use stub shaft conversions that can cause catastrophic oil pump failures.
