9.4L and 751 PS: Old Hemi V8 reinvented as a modern crate engine

Prestige Motorsports has presented its own take on the classical second-generation Chrysler Hemi V8 engine from the 1960s. The mill has impressive volume, power and especially torque and produces far less emissions than its ideological predecessor did. You can already order it in a crate form ready to be installed in just about any car (but preferably an American muscle car).

The Mk2 Hemi V8 saw the light of the day in the year 1966. It featured seven whole liters (426 cubic inches) of displacement and delivered a manufacturer-stated 431 PS (425 hp / 317 kW). It was an open secret back at the time that Chrysler ran the dyno tests at 5,000 RPM in order to facilitate certification and insurance. Revved up to 6,000 RPM, the same mill was easily capable of 507 PS (500 hp / 373 kW), multiple reports say.

Well, these numbers are undeniably cool but they pale in comparison to this modern monster. It commands 9.4 liters of displacement and outputs a nominal 710 PS (700 hp / 522 kW), but Prestige Motorsports has a video on its channel where it makes 751 PS (741 hp / 552 kW) on the dyno. What’s even cooler, it churns out mountain-moving 945 Nm (697 lb-ft) of torque. This is made possible thanks to Edelbrock aluminum headers, a roller-bearing camshaft and roller rockers, as well as many other modern components. The block is cast-iron by default, but you can choose aluminum if weight is your priority.

The price of a fully built and tested engine like this stops just short of $31,000.
