Mopar will get racing and off-road enthusiasts buzzing with its enhanced lineup of engines and components, which includes the industry’s first aluminum HEMI® engine blocks. Mopar will offer three aluminum versions based on the popular 6.1-liter block, all of which are up to 98 pounds lighter than the cast-iron production version found in the company’s SRT8® products.
The first all-aluminum option is a 6.1-liter HEMI block—a direct replacement for the factory production cast-iron 6.1-liter HEMI engine block. The second option is prepped for a 426 cubic-inch (similar to the 6.9-liter) engine and the third option is an engine-builder’s special or “X Block,” which has rough-machined bores that allow for up to 468 cubic inches (similar to the 7.6-liter engine).
Beyond the new aluminum HEMI engine blocks, Mopar will continue to support the traditional enthusiast with a broad range of HEMI crate engines including the 6.1-liter V-8, 5.7-liter V-8, 426 cubic-inch V-8, 472 cubic-inch V-8, 528 cubic-inch V-8, plus a new 572 cubic-inch V-8. With 650 horsepower and a monstrous 660 lb.-ft. of torque, the 572 cubic-inch HEMI is the centerpiece of Mopar’s crate engine program. It continues the heritage of the 1960s HEMI engines made popular in vehicles including the Plymouth Barracuda “HEMI ’Cuda”, Plymouth Satellite and Dodge Charger.
Mopar also will introduce a new 4.7-liter I-6 Stroker long block, a powerful upgrade for the 4.0-liter I-6 made famous in Jeep vehicles built from 1991-2006. Since off-road enthusiasts appreciated the dependability and performance of the previous 4.0-liter engine, Mopar developed a more powerful engine that delivers an expected 265 horsepower and 290 lb.-ft of torque. The engine will fit in any Jeep vehicle previously equipped with the 4.0-liter I-6 engine.
