Who Requires Boost When You Possess 9.4 Liters Of Unadulterated Hemi Insanity | Carscoops

      Prestige Motorsports offers a contemporary rendition of Chrysler's iconic muscle V8, generating over 700 horsepower while maintaining street usability.

      Founded in North Carolina, Prestige Motorsports specializes in modernized adaptations of Chrysler’s 426 Hemi V8, now enhanced to a 572 Hemi configuration which adds 2.4 liters and features an alloy block paired with matching heads. A forged bottom end ensures this V8 handles its robust output of 741 horsepower with ease.

      In the late 1960s, selecting the Hemi V8 option for your Dodge or Plymouth was a costly way to secure the title of the fastest vehicle in town, provided you could keep its dual carburetors tuned and maintain traction.

      Indeed, it was a powerhouse, but one might wonder how much more formidable the classic Hemi could be with today’s advanced technology and materials. One shop in North Carolina seems to have found the answer, albeit at a considerable price.

      Chrysler produced three iterations of the Hemi V8: the first in the early 1950s, the second in the mid-1960s, and the third in the early 2000s. Prestige Motorsports’ 572 Hemi draws inspiration from the 1966-71 426 Hemi, a hallmark of muscle car history.

      Originally equipped with two Carter four-barrel carburetors, the 7.0-liter model was rated at 425 hp (431 PS), though some assert this figure was intentionally low for insurance reasons and homologation by recording peak output at 5,000 rpm. In reality, it likely delivered close to 500 hp (507 PS) when allowed to rev up to 6,000 rpm.

      The old gross horsepower ratings, established when engines were tested without exhaust restrictions and ancillary components, were phased out in 1971 in favor of more accurate net horsepower figures comparable to modern standards. During this transition, Chrysler reported both gross and net stats, stating that the Hemi produced only 350 hp (355 PS) net.

      Thus, even with some additional revs, it would likely not exceed 400 hp by contemporary metrics. While impressive for 1966, it pales in comparison to today’s supercharged Hellcat, which boasts over 700 hp (710 PS).

      This is where Prestige Motorsports’ Hemi takes the spotlight. With an additional 2.4 liters over the already sizable original, the 9.4-liter 572 Hemi is constructed from top-quality components and features a robust forged bottom end to ensure consistent performance over time.

      Standard features include Edelbrock aluminum heads, contributing to a weight reduction compared to a stock Hemi. Additionally, buyers have the option to replace the cast iron Indy block with an aluminum version for even greater weight savings.

      Designed for durability and power, Prestige claims a dependable output of 700 hp. In a recent video posted on the company’s YouTube channel, a particular 572 build demonstrated 741 hp (751 PS) at 5,900 rpm and an impressive 697 lb-ft (945 Nm) of torque at 4,400 rpm.

      While this crate engine can be directly installed into vintage Mopar muscle cars, Prestige wisely recommends ensuring the rest of the vehicle is equipped to handle such power.

      Priced around $31,000 for a fully assembled, dyno-tested engine, this represents a significant financial endeavor. However, envision the thrill of surprising modern drivers by placing one of these engines into an unassuming model, such as a four-door Plymouth Satellite with steel wheels.

      For those who may want even more power, Prestige also offers the extreme forced-induction-capable Power Adder 572 Hemi, boasting a capability of over 1,000 hp (1,014 PS).
