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!
