HEMI Crate Engines

A2Speed carries both stock Mopar engines and custom stroked out HEMI crate engines. Each comes as a full engine from the intake to the oil pan. All of the accessories like valve covers, front cover, throttle body, etc. are included. This is ideal for a resto mod project where you don’t already have the accessories to swap over.

Our Mopar motors include the VVT eagle 5.7L, the 6.4L 392 apache, and the supercharged 6.2L hellcat. Custom tuning solution are available for each courtesy of a Holley dominator system which can be added at the time you order.

As mentioned above, A2Speed also carries a line of custom Ray Barton built stroker motors. These start with a completely forged rotating assembly; a Molnar 4340 crankshaft, Molnar 4340 connecting rods, and 2618 CP-Carrillo pistons. Both the head and main bolts are upgraded to studs, adding the extra security needed for extreme stress environments such as high boost forced induction applications. A Comp cam is chosen specifically for your applications needs. The heads are ported, and resprung by Thitek performance, our industries premier company for HEMI head technology. Couple all of these top shelf components with Ray Barton’s 30+ years of engine building experience and you have a truly unique and reliable, high performance motor. To top it off we back our line of strokers with a 3 year / 36,000 mile warranty. Learn more about why your stroker should be Barton built!

  • How We Do It
  • Our Quality
A2Speed is an employee owned automotive performance parts company, specializing in the Gen III HEMI engine and the cars & trucks it powers. Just like you we are Hemi enthusiasts, and like you we are only interested in proven performance solutions. Good enough isn’t. People who invest in performance modifications want parts that last decades, not years. The effort is only valuable if the result is better than good enough, and frankly these days that’s hard to do.

A2Speed’s GEN III HEMI Background

Many of us at A2Speed have been working on the Gen III since its inception. As a team we are immersed in the Hemi world. We own, drive, modify, race and occasionally…break them. We use this experience to create SOLUTIONS, not just parts. Automotive engineering has advanced such that it is often difficult to improve on the work done by the OEMs. Difficult, not impossible. Utilizing advanced 3D modeling, CFD and stress simulations coupled with rapid prototyping, allow for the development of specialized parts that would be impractical at OEM volumes. Solutions validated with real world testing. Craftsmen level quality; and because we don’t have the layered overhead, our prices are often at or below the OEM price.

Advanced Aerospace Grade Machining

Production manufacturing is performed by partner companies that have proven track records for quality and timely deliveries. We look for certifications such as ISO-9001 and AS-9100 along with ITAR and GIDEP registrations. Several of the companies we work with regularly supply major aerospace firms and the DOD. Why use outside machining services? So that you get a better part at a better price. By utilizing only the machine cycles we need, and leveraging the superior skills and years of experience, A2Speed can give you exceptional quality at truly affordable prices.
