This 797-HP Hellcat Redeye Engine Ships on a Pallet — And Bolts Straight Into Any Challenger

A Cleveland engine shop is turning genuine 797-horsepower Hellcat Redeye HEMIs into complete, pre-wired units that ship on a pallet and bolt into nearly any Challenger. The clip proves the concept about as literally as possible, firing the motor with nothing else attached. Here’s what’s actually inside the swap, and why Dodge never sold this powertrain as a standalone option.

Cleveland Power & Performance did not build a car for this video — they built an engine that arrives on a shipping pallet, already wired and accessorized, and drops into practically any Dodge Challenger in an afternoon. The unit is a genuine SRT Hellcat Redeye 6.2-liter supercharged HEMI, rated at 797 horsepower and 707 lb-ft of torque straight off the factory spec sheet, bolted to its own wheeled skid with the harness, accessories, and even a battery already mounted. The shop fires the engine while it is still strapped to the pallet, and it snarls to life like a running car with no chassis wrapped around it — no hood, no fenders, nothing but 797 horsepower sitting on a piece of wood. Commenters compared the rig to a life-support machine and joked it might be the fastest pallet in the warehouse, and they are not exaggerating about the speed part. This is the same engine that made the 2019 Challenger SRT Hellcat Redeye one of the quickest production muscle cars Dodge ever built, except now it ships straight to a customer’s garage instead of a dealership lot. The real question is not whether the thing makes power — it is why anyone builds an engine this way instead of just buying the finished car, wiring harness and all.

Why a “Pallet Motor” Is the Easiest 800 Horsepower You Will Ever Bolt In

Cleveland Power & Performance calls these builds turnkey pallets, and the name is literal. Every accessory a Hellcat Redeye needs to actually run — alternator, power steering pump, belt drive, wiring harness, even the PCM and fuel system components — comes pre-installed and pre-configured before the engine ever leaves the shop. That is the entire pitch: instead of sourcing a bare Hellcrate Redeye block through Mopar’s Direct Connection catalog and then spending weeks chasing down the dozen ancillary parts that make a factory HEMI actually function outside its original car, a buyer gets a complete unit that only needs motor mounts, a driveshaft, and fuel and exhaust connections to come alive in a new home. The shop’s business is built entirely on repeat customers and word of mouth from people who never want to touch a wiring diagram.

The video demonstrates that self-sufficiency directly, cranking the engine on the pallet with nothing else connected — a flex that only makes sense once you understand how many swap projects stall out waiting on some overlooked sensor, bracket, or wiring gremlin. Viewers picked up on it immediately, with several comments calling it “literally the definition of a crate engine” and praising the idea of proving an engine runs before it ever ships to a customer who may never set foot in the shop. For a company whose entire business model depends on selling engines sight unseen, that proof-of-life moment is doing real work — and it is also just satisfying to watch 707 lb-ft of torque idle on a piece of plywood.

The Factory Engine Dodge Almost Didn’t Sell You

The Hellcat Redeye did not exist as its own model until Dodge introduced it for the 2019 model year, positioning it above the standard 707-hp Hellcat by borrowing hardware developed for the Demon, Dodge’s drag-strip-only special edition. Instead of the standard Hellcat’s supercharger, the Redeye uses a larger 2.7-liter unit, along with dual fuel pumps, an upgraded intake with twin snorkels poking through the hood, and a “Power Chiller” system that borrows cold air from the air conditioning to keep intake temperatures in check during hard, repeated runs.

The result was 797 horsepower and 707 lb-ft of torque from the factory, paired exclusively with an 8-speed automatic transmission — Dodge never offered a manual on the Redeye. Those numbers were enough to push a widebody Redeye through the quarter-mile in 10.8 seconds and to a claimed 203-mph top speed. A new one stickered just under $70,000 before fees, with the gas-guzzler tax and destination charge pushing the out-the-door price closer to $73,000 — real money, but figures that put a car buyers could finance at a Dodge dealership within shouting distance of six-figure exotics.

Dodge also never sold the Redeye’s engine as a standalone option for any other car, which is exactly the gap that created a market for shops like Cleveland Power & Performance. Enthusiasts who wanted this specific combination of supercharger, tune, and output in something other than a factory Challenger or Charger had no factory path to get one. Used Redeye donor cars command a steep premium precisely because the engine underneath them is this desirable, and salvage-title examples — cars written off after an accident but with an intact drivetrain — became the raw material for an entire cottage industry of engine pulls and rebuilds.

What a Turnkey Swap Gets You That a Used Redeye Challenger Can’t

Buying a used Redeye Challenger gets you the engine, but it also gets you everything wrapped around it — mileage, accident history, and whatever a previous owner did or did not do to the rest of the car. A turnkey pallet swap decouples the two. Buyers can put a genuine, verified-running Redeye HEMI into an older Challenger, a Charger, a Ram, or in some builds a completely unrelated vehicle, without inheriting someone else’s chassis problems, interior wear, or accident repairs.

That flexibility is also why the pallet format matters more than it might look like it should. A running, fully accessorized engine that gets started and tested before it ships removes most of the guesswork that normally turns an engine swap into a gamble. Instead of buying a partial engine and hoping the missing parts and tuning come together on the shop floor, a customer is buying a finished, proven system — the hard part has already been done by someone else, on video, for anyone to see before money changes hands.

The Restomod Market These Engines Are Reshaping

Turnkey Hellcat swaps have become one of the biggest stories in the restomod world over the past several years, and the Redeye variant sits near the top of that market because of its factory-backed numbers. Builders dropping a 797-hp HEMI into a decades-old muscle car chassis — a first-generation Challenger, a Charger, even non-Mopar builds — get factory-level reliability and a documented power figure instead of a custom stroker combination with unknown durability. That combination of known output and forced-induction simplicity is a big part of why Hellcat and Redeye swaps show up constantly across build shops and YouTube channels covering the restomod scene.

It is also changing how people shop for donor engines in the first place. A pallet build like this one gives buyers a way to skip the salvage-yard treasure hunt entirely, paying a premium for the assurance that the engine has already been tested rather than betting on an unknown unit pulled from a wrecked car. Whether that convenience is worth the markup is exactly the kind of debate playing out in the comments under videos like this one — and it is a big part of why a company that builds engines on wooden pallets can turn the process into entertainment in its own right.

The Insurance and Registration Questions Nobody Skips

Swaps like this one raise real-world questions that go beyond horsepower. Because a transplanted Redeye HEMI did not come from the factory in whatever car it ends up in, owners often find that mainstream insurers ask more questions about a modified drivetrain once the swap is disclosed, and coverage sometimes requires a specialty policy. Emissions and registration rules also vary significantly by state, and a swapped engine that is not paired with its original vehicle’s certification can complicate a smog check or title inspection depending on where the car ends up registered.

None of that stops the swaps from happening — if anything, it is part of why shops that document the process, keep records, and sell a verified, running unit have an advantage over someone buying a mystery engine off a classifieds listing. A buyer who can show exactly where an engine came from and that it was tested before installation is in a much stronger position if a state inspector or an insurance adjuster ever asks questions about what is actually under the hood.

For shoppers, the practical takeaway is to treat a turnkey pallet the way you would any other major purchase: ask for documentation of where the engine came from, whether the donor vehicle carried a clean or salvage title, and what warranty coverage, if any, comes with the pallet itself. Reputable shops in this space are used to fielding those questions, and a company willing to run an engine on camera for anyone to see is usually also willing to hand over the paperwork that backs it up. That transparency, more than the horsepower number itself, is what separates a serious turnkey builder from someone just flipping a used engine for a quick markup.
