This Mopar A148 Experimental Hemi is a remarkable modern interpretation of Chrysler's legendary racing HEMI architecture, built by Arruzza Performance to showcase the ultimate potential of the hemispherical-combustion-chamber V8. Designed with competition in mind, the engine combines classic Mopar heritage with contemporary engineering, resulting in a powerplant that is as visually striking as it is mechanically impressive.

One of its most distinctive features is the dramatic cross-ram intake manifold. This configuration utilizes long, carefully engineered intake runners that help optimize airflow and cylinder filling, improving torque and horsepower across the operating range. The cross-ram design also gives the engine an unmistakable appearance, recalling the exotic induction systems found on some of Chrysler's most famous racing engines from the muscle car era.

Finished in a vibrant yellow paint scheme and displayed on an engine stand, the A148 immediately captures attention. Massive cylinder heads, oversized intake runners, and the unmistakable proportions of a racing HEMI emphasize the engine's purpose-built nature. Every component reflects a focus on strength, airflow, and high-performance capability, making it a centerpiece for both racers and enthusiasts.

Like the legendary 426 HEMI that inspired it, the A148 belongs to a lineage often referred to as the "Elephant Engine." The nickname originated from the engine's imposing physical size and extraordinary power output, characteristics that helped make Chrysler's HEMI engines dominant forces in drag racing, NASCAR, and other forms of motorsport. The A148 carries that tradition forward, serving as a modern tribute to one of the most famous racing engine families ever created.

“A modern experimental HEMI that honors the Elephant Engine legacy with cross-ram induction and uncompromising racing spirit.”

Here is a cool shot of one of the Tuatara engines going together SSC North America before you see the plenum, intercooler, throttle body, etc. on it, this is a shot of the runners with the dual injectors per cylinder.

EVERY TIME A FORD ENGINE GETS TOO GOOD…
SOMEBODY CALLS AN EMERGENCY MEETING. 🚨

It happened to the 427 SOHC Cammer.
Banned before it turned a wheel in competition.

It happened to Bob Glidden.
Dominated Pro Stock for a decade… rules tightened until the advantage disappeared.

It happened to Bill Elliott.
212 MPH at Talladega. NASCAR’s response? Restrictor plates. Still there today.

It happened to Snot Rocket.
3.762 in LDR… and within weeks: +300 lbs, no intercooler, no lockup.

Now Ford’s going to Le Mans with a naturally aspirated 5.4L Coyote V8.

Place your bets now on how long before the rules “need adjusting.”

Because this isn’t a pattern anymore.

2,000 horsepower. 9:1 compression. Hydraulic roller cam. Daily-driver reliability. Thirty years ago, this would have sounded impossible. Today, it’s reality. The technology we have is absolutely incredible. 🔥🏁🔧💪🏻
