Reviewing The EngineLabs’ 1,200HP Giveaway Gen-III HEMI

If you’re reading this before April 2, 2024, you can still get entered to win this 1,200-horsepower Gen-III HEMI engine built by Late Model Engines and Summit Racing. If you’re already entered, and have maximized all possible entries, you might want to go back to www.enginelabsgiveaway.com for a few more entries. We’ve been hiding extra entry codes in the giveaway engine articles over the past few months, so if you’ve already found all five, awesome. If not, here they are:

ELEPHANT
WEDGE
HEMISPHERICAL
TWINSCREW
FIREDOME

Each one of those codes on the giveaway website will get you an extra entry into the giveaway. With that said, let’s move on to looking at the engine itself.

One of the really neat features of this engine is that it was entirely assembled live on the floor of the 2023 PRI Show floor.

The 1,200-Horsepower Gen-III HEMI

If you are in a heavy reading mood, here are all the links to the previous articles we’ve written on the Giveaway HEMI engine. If you’re not in a reading mood, we’ll summarize the build here.

Starting with a cast-iron BGE block, LME machined the surfaces and opened the bores up to 4.095 inches. They then fitted a set of Energy Manufacturing’s billet main caps and ARP main studs. The factory oil squirters were blocked off, and King Engine Bearings were fitted.

A Callies Compstar forged 4340-steel 4.050-inch-stroke crankshaft was dropped in, accompanied by Callies Ultra Enforcer 6.125-inch rods made from forged 4330V steel. Hanging off those rods are a set of Diamond Pistons’ Hemi2K 2618 forged pistons held in place by some beefy Trend thick-wall wrist pins and Total Seal piston rings. An ATI Super Damper eliminates torsional vibration, while under the engine, a Milodon windage tray designed for the Drag Pack cars was fitted along with the Drag Pack oil pan and pickup tube, coupled with Melling’s Hellcat oil pump.

Moving to the top end, a set of Thitek GenIIIH “Bear” cylinder heads were fitted with ARP head studs and sealed with a pair of Cometic MLX head gaskets. A Cam Motion VVT Camshaft was installed along with the factory timing set, but with the VVT locked out. Johnson short-travel hydraulic lifters were then dropped into the lifter bores with 3/8-inch, .080-wall Cam Motion pushrods sitting on top of them. Then a set of Jesel shaft bolt-on rockers were fitted with a set of Stanke Motorsports shaft braces and covered with a set of LME’s brand-new billet HEMI valve covers.

The core of the engine’s power comes from a Gen-6 3.8-liter Whipple twin-screw supercharger that was just released at the PRI show. Performance Distributors Sultans of Spark coils provide energy to the Brisk Silver spark plugs, while Fuel Injector Clinic 1,440cc/min injectors provide the fuel needed to make big power.

Once the engine was completed live on the PRI Show floor, it went back to LME, where we rejoined the engine on LME’s dyno. There, we first ran the engine with a set of OEM Hellcat manifolds and made 1,199 horsepower. A quick swap to Kooks 2.0-inch-primary stainless headers, netted us another 68 horsepower, with our final total coming out to 1,267.3 horsepower, all on 93-octane pump gas with a little BOOSTane professional added to it.

Now, this engine can be yours. All it takes is signing up for free at www.EngineLabsGiveaway.com and a little bit of luck on your side.
