Direct Connection, the factory-backed performance parts arm of Stellantis, unveiled six new HEMI crate engine packages at the 2026 SEMA Show on November 3. The lineup starts with a 385-horsepower, 345-cubic-inch V8. At the top, a supercharged engine is rated at up to 1,025 horsepower on E85. Each package pairs the engine with the electronics needed to run it.
That last part is the real news. A modern HEMI swap needs more than the engine, because it also needs wiring, a computer and a pedal. These packages put those pieces in the same crate, and they come with a factory warranty.
Orders open early next year, and prices are still to come. Here is what each package includes and how the lineup steps up.
What comes in the HEMI crate engine packages
According to the Stellantis release, every package combines a crate engine with a matching controller kit. The kit includes the engine wiring and a power distribution center. It also has a flashed powertrain control module, oxygen sensors and an accelerator pedal.
Automatic versions also add a shifter and a brake switch. Then there’s the collector touch, because each engine ships in a branded crate with a serialized fender tag.
The packages are designed to bolt up to Direct Connection’s new TorqueFlite 8HP90 automatic crate transmissions or a TREMEC Magnum manual. However, the two supercharged engines require the 8HP90 automatic. Stellantis also says the lineup offers flex-fuel capability.
The 345 and 392: Street Strip and Super Stock
Four of the six packages use naturally aspirated engines. The 345 Street Strip and 345 Super Stock both make 385 horsepower and 417 lb-ft of torque, with a 10.5:1 compression ratio. Similarly, the 392 Street Strip and 392 Super Stock both make 485 horsepower and 475 lb-ft, at 10.9:1 compression.
So what does Super Stock add? The release says those versions get Redeye valve springs, an SRT Hellcat oil pump and an SRT oil cooler. The 345 Super Stock also gets a larger SRT oil filter. In other words, the power is the same, but the hardware is built for harder use.
Motor1 adds another difference for the smaller engine. It reports that the 345 Street Strip uses a remanufactured block, while the 345 Super Stock gets a new one.
Hellcrate Redeye: up to 885 horsepower
The fifth package steps into supercharged territory. The Hellcrate Redeye 6.2L Super Stock displaces 376 cubic inches and uses a 2.7-liter IHI twin-screw supercharger. It runs 9.5:1 compression. Stellantis rates it at up to 885 horsepower and 787 lb-ft in High Octane Mode.
It also borrows parts from its bigger sibling. For example, the release lists a Hellephant 426 supercharger pulley and a 180-degree thermostat as extras. Motor1 notes that the full rating requires higher-octane fuel.
Direct Connection already has one showcase for it. A restored 1967 Plymouth GTX, first shown at SEMA 2024, returns this year as the first build with the Hellcrate Redeye package and an 8HP90 automatic.
Hellephant C170: the 1,025-horsepower top end
At the top sits the Hellephant C170 6.2L Super Stock. It uses a 3.0-liter IHI supercharger with a 3.02-inch pulley and a 105 mm throttle body. With E85, Stellantis rates it at up to 1,025 horsepower and 945 lb-ft.
Running on ethanol takes extra parts. As a result, this package adds an ethanol sensor plus an upgraded fuel rail and injectors for E85. It also gets upgraded pistons and billet steel main caps. Motor1 says the ethanol sensor lets the controller adjust timing and fueling as the blend changes, and that 1,025 horsepower isn’t available on pump gas alone.
The engine itself isn’t new. Back in November 2023, Hagerty reported that Direct Connection would sell a Hellephant C170 crate engine, the same 6.2-liter supercharged V8 used in the Challenger SRT Demon 170. At that time, Hagerty listed it at $27,695 fully assembled. What’s new now is the turnkey package around it, with the controller kit and a warranty.
Warranty, timing and price
The warranty is the headline for many builders. Stellantis says each crate engine package with its controller kit carries a three-year, 100,000-mile warranty. Meanwhile, the TorqueFlite 8HP90 crate transmissions get 12 months or 12,000 miles.
Tim Kuniskis, head of American Brands, SRT Performance and the Direct Connection division at Stellantis North America, summed up the idea briefly. “Our philosophy is simple: one part, one solution,” he said.
Builders will have to wait a little longer for numbers on the invoice. Stellantis says the six HEMI crate engine packages arrive in the first quarter of 2027, and it has not yet announced pricing.
