Product 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!
Race-Proven Results For You EVO
All our
race engines are individually handcrafted at AMS using the same care as the
ones found in our world record holding street and race cars. When you
choose an AMS engine you are investing in the knowledge gained from assembling
1000's of race engines over the past 10+ years. With over 200 Victories
in Motorsports over the last 3 years alone, it is clear that AMS is the only
choice for your car!
Built To A Higher Standard
Just
like our 1500 HP Alpha GT-R's and 1400 HP AMS Drag EVO, 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 engines is our Race Balance Shaft Eliminator
Kit. We do not use stub shaft conversions that can cause catastrophic oil pump
failures.
All New Components Utilized For Reliability And Peace Of Mind
We found as the EVO 4-9 platform has gotten older there are fewer and fewer good core blocks and
cranks out there. In order to keep the
highest standards for reliability in our engine program we have chosen to use only
new blocks, aftermarket cranks and oil pumps in our builds. This
is not an off the shelf combination, no expense was spared. It is stuffed full of only the absolute BEST parts available. We feel the added
cost up front is much cheaper than having to build an engine and install it
twice, not to mention the down time and frustration. While other engine programs offer cheaper
alternatives, we make sure your engine is ready for years of beating down your
competition the first time around!
