Listen to the WORLD'S FIRST 427 Cubic Inch Lingenfelter Powered C8 Corvette!

We came across the world's FIRST C8 with a brand new 427 cubic inch engine in it at the @LingenfelterLPE booth at Hyperfest 2024!

Come along with us as we talk to Mark Rapson of Lingenfelter about how they developed this BEAST of an engine, progress made so far shaking it down post-install, and we even get to hear this amazing engine roar to life!

Special thanks to Lingenfelter for providing the video clips in parts of our video - you guys rock!

From Lingenfelter's website:

The iconic 427 cubic inch engine for the C8 Corvette is the most powerful naturally aspirated C8 engine available. The Lingenfelter Eliminator Spec S 7.0L LT2 Engine makes over 700 HP on 91 octane gas!!!!

The Lingenfelter 427 Eliminator Spec S Engine was developed to give C8 owners the sound and feel of big cubic inch and high torque naturally aspirated power for their mid-engine Corvette. A mind-blowing 700+ horsepower at 6700 RPM and 600+ lb. ft. of torque at 4800 RPM makes this engine the highest power NA available for the C8.

Working with industry leader and LPE development partner Callies, the two developed a unique forged rotating assembly allowing the use of a 4.00 stroke 8 weight crank with special counterweights that work within the factory oil pan and retain all factory oiling and scavenging systems. The block is CNC blueprinted and sleeved allowing a special 4.125 piston by MAHLE. Cylinder heads are factory casting CNC ported by Lingenfelter specific to the LT2 7.0L program.

A new camshaft was developed for the 7.0L engine that optimizes the power band to work within the DCT transmission's torque and shift parameters. The new cam gives great power delivery for excellent drivability. The engine makes this great power with both stock and aftermarket manifolds.

This winning combination allows for both Coupe and HTC C8 Corvette owners to enjoy the big power of the world’s first 7.0L 427 LT2 naturally aspirated engine built by Lingenfelter.

We owe the modern day 427 to John lingenfelter! R.i.p John.

[mchristr]

Because the 7 liter displacement is the internal swept volume of the engine. It doesn't at all change the external dimensions.

[LingenfelterLPE]

Great video, Fresh Vintage! Thank you for taking the time to chat with Mark Rapson about the build & showing off our performance passion project!

[farncoisbisson]

4 inch stroke 4.125 piston.. oh wow so hard that literally every shop are doing it. That 8.1 c8 is more impressive

[samholcombe]

How they fit a 427 in there? Because the outside dimensions are the same for a 4.8, 5.3, 5.7, 6.0, 6.2 and 7.0

[christianwolf]

Alter Falter ist das ein Sound 🤣🤣🤣🤣 mit 7.1 😱😱😱😱 der Hammer 👌👌😁😁

[brianholcomb]

Engines physical size doesn’t change! Only the bore & stroke! Check around, because a guy has already done an actual big block Corvette! It’s on YouTube!

[kinggorhk]

It is awesome. Does it work with E-Ray too?

[englandtra]

It fit because it’s the stock motor that came in it just different rods pistons crank and sleeves

[boblevine]

Did he say the 427 “Goes back to the very first one (Corvette)” ? Umm…???

[DavidWenger-twdz]

Careful guys, Race Proven Motorsports in Delaware, dyno ed Lingenfelters Corvette and the cost to hp gain was a little to be desired. If you have Lingenfelter money, you have Late Model Racecraft money in Houston showing strong gains. My Camero is scary to me now! Thanks Steven!

[randallmason]

Is that a VIR bib? If so what event is this? That car will be a beast around the track!!

[uberdriver]

There is a old guy that builds corvettes with a YouTube channel. He put a real big block in his c8. It's a 427 or 454. Not a ls based engine.

[NOCAN]

I am all in....
I can't run the miles up on this factory Z51 engine fast enough...

[braddavidson]

It's not the old big block. LS is a different story

[suzukiyesteryear]

That antique lump will be bending the frame…

[leehrh]

427 goes all the way back to the very first corvette? Are you sure about that?

[emmetband]

Actually the first Corvette's were powered by a straight six.

[merylpelosi]

Because it's about the same size as a 5.3? I dunno.

[nrakma]

Oh good, a step backwards. What’s next, a Flathead?
