A2Speed / Ray Barton HEMI Engines
Current A2Speed / Ray Barton Engine Specs
A2Speed, in conjunction with Ray Barton Racing engines, is bringing you a whole new line of GEN III HEMI engines. We are currently offering 5 different base builds that will be available in three different configurations. These various specs will be based on 5.7L, 6.1L, 6.2L, and 6.4L GEN III HEMI blocks.

The Short Block Assembly Process
Every HEMI we make goes through a very labor extensive process. Each short block will be hand built in the USA by Ray Barton. How the engine is built and the meticulous efforts of the engine builder really determine the overall reliability of your engine. In this industry, experience is paramount and no one has more experience building HEMI's than Ray Barton. He has built high performance HEMI’s for well over 30 years.
The short block creation process starts with a core torn down to the bare block. This core is then cleaned, inspected and then precision measured on a 5 axes Rottler CNC / CMM block mill. Oil galleys are cleaned and prepped, including edge de-burring and chamfering. Cylinder bores are radiused, and the block is stroker clearanced if necessary. Then the block moves to the machine shop where the it is decked, bored and line bored (if necessary) on the CNC machining center. Final block work includes diamond honing the cylinder bores on a CNC honing machine with deck plates. The rotating assembly is balanced, then the block and rotating assembly make their way to final assembly. In this, the studs, main bearings, rod bearings, pistons & piston rings, and connecting rods are all professionally installed maintaining a .005” tolerance. Finally the block is painted and prepped for shipping or building into a long block or crate engine.
High Performance HEMI Components
All of our HEMI engines come with top of the line performance components. We found all of the best products on the market today and combined them to make a truly special line of engines. Some manufactures include Molnar, Thitek, CP-Carrillo, Diamond, King Bearings, ARP, Comp Cams, PSI Valve Springs, Commetic, & many others. Each of these manufactures represent countless hours of R&D, and years of experience producing extremely high performance parts for the HEMI community.
We use Molnar 4340 forged crankshafts in all of our HEMI engines. They are heat treated, shot peened, nitrated and 100% mag particle tested. These features greatly improve tensile strength, fatigue life, and wear resistance.
We use Molnar connecting rods as well. They are also made of a 4340-forged material, shot peened, and heat treated. Like the crank shaft these features improve tensile strength and fatigue life. Another important feature is that all of the Molnar rods we put in our HEMI’s come with a wear resistant bronze bushing to increase wrist pin life. Molnar rods come standard with ARP 2000 rod bolts.
For pistons, we either use Diamond or CP-Carrillo 2618 forged pistons. 2618 aluminum is a malleable low silicone based material that allows the piston to withstand extreme loads such as detonation more effectively. Forged pistons are a must for boosted applications, and particularly for 6.4L engines. These pistons come with steel top rings and optional coatings are available.
ARP Head and Main Studs
ARP main and head studs are used in all our HEMI engines in an effort to ensure that both the main caps and heads are secured to the engine properly. The studs are made of stronger material that prevents deformation over time. This strength prevents issues such as the heads lifting due to worn out head bolts.
CNC Ported Heads by Thitek
All of A2Speed engines come standard with CNC ported heads. All of our heads are ported by Thitek, the first company to produce a 100% aftermarket heads for the HEMI community. A2Speed’s CNC ported heads come with high lift PSI valve springs, tool steal retainers, new locators, and Viton valve seals. The Valve guides are hone and performance prepped and a multi angle valve job is performed. Thitek is the best in the business, and has an incredibly intricate understanding of GEN III HMEI head technology.
High Performance Comp Camshaft
A2Speed engines come standard with a high performance Comp Cam. We match up the appropriate camshaft based on your desired outcomes and intended use for your new HEMI engine. All factors such as lobe separation angle, RPM range, intake and exhaust duration, and lift are taken into account when selecting the appropriate cam for your HEMI.
A2Speed / Ray Barton HEMI Engine Configurations
We offer our motors in 3 different configurations, short blocks, long blocks, and crate engines. A short block comes with the new rotating assembly already installed in the block, and requires the customer to finish installing the remaining components such as the camshaft and heads. A long block is a short block with the timing set, oil pump, heads, and valve train already installed, the customer just has to transfer things like the front cover and engine dress over to complete it. Crate engines come completely assembled with OEM accessories already installed, which is perfect for resto mod guys.

A2Speed’s GEN III HEMI BackgroundMany 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 MachiningProduction 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.
