• Production starts for Mopar’s new 426 ’Elephant’ Hemi V8 engine

The Performance Racing industry show came and went with a series of new parts for all of our racing needs. Among the most notable of these items was Mopar’s new 426 ’Elephant’ Hemi V8 engine. This engine is all aluminum and delivers an impressive 540 HP and 530 ft.-lbs. of torque, all for a bargain price of $13,675. Production for the engine has already started.

Along with the new 426 engine, Mopar brought out the new 2011 Mopar Challenger V-10 Drag Pak. The drag pak comes with a 8.4-liter 512 cubic-inch engine with a 2-speed automatic transmission. Based on the 2011 Dodge Challenger and finished in a Stock Eliminator and Super Stock configuration, the 2011 Mopar Challenger V-10 Drag Pak is the first and only 500-plus cubic-inch V-10 drag-race package car.

Alongside the 426 ’Elephant’ Hemi V8 engine and the V10 Drag Pak, Mopar also brought valvetrain tie bars, a rear strut tower, midget race cylinder head, aluminum engine blocks, cylinder head stud kit, cold-air intake, W2 heads, and a Gen III distributor kit to the show. All of these parts can be ordered individually to increase your car’s performance.

New Moparized rides and 10 new Mopar performance parts will also be on display.

The 2011 Mopar Challenger V-10 Drag Pak, recently named to the 2011 “Hagerty Hot List” of collectible cars, will be on display on the Mopar Image Center stage at PRI. Fans will have the opportunity to pose for an eShot photo on Thursday and Friday with the new rear-wheel drive race car, approved for NHRA Stock and Super Stock competition.

The new Drag Pak will be joined in the Mopar Image Center by a Moparized 2010 Ram Laramie Crew 4x4 Diesel and the Mopar ’10 Challenger, the first-ever Mopar edition of a Chrysler Group LLC vehicle. The Mopar exhibit on the PRI show floor will feature five other examples of Mopar steel:

  • Mopar Ram Runner, Mopar’s premier pre-runner kit
  • Mopar Direct Connection Test Lab Vehicle, a rolling test lab of new parts and ideas
  • Dodge Viper ACR-X, a factory-built race car ready to romp
  • Sox & Martin’s 1972 Pro Stock Dodge Demon, a true piece of Pro Stock history
  • Kenny Wayne Shepherd’s new 1964 Dodge 330. Powered by a Mopar Gen 3 426 all-aluminum HEMI crate engine, this car mixes old-school classic with new-school performance

Mopar stars, past and present, will sign autographs and meet fans at PRI. Mopar racing legends “Big Daddy” Don Garlits and Herb McCandless will make an appearance in the Mopar exhibit on Thursday, Dec. 9, at 2 p.m. EST.

That’s good to know more about V8 engine. I actually been thinking of its effectiveness. Well, am still reading the car’s added special features. I’m too curious on high powered cars.

I agree with you Silvestre_Wall. Four-cylinder is not a modern technology. And I think this engine doesn’t offer an exceptional power since it can produce up to 540 hp only.

I think you can’t consider the four cylinder a modern technology. I rather accept V10 as the replacement of this.

I put the manual transmission into low and with the clutch engaged I cranked the engine. The starter motor pulled us across the intersection, up a slight incline, and out of harm’s way. pulling approximately 2 tons total.

Another time we were on our way to Cape Cod, towing the Cox with the ’75 Audi. I ran out of gas in the middle of an intersection, blocking traffic.

impressive, but it would be better if they used a CRDi technology.

Chrysler... Please put this 426 in the new SRT-8 models!! Especially the coming Jeep GC SRT8, that would be a nice comparison with the Porsche Cayenne Turbo!

This is pretty impressive. Chevy’s current 7.0 liter engine (427.8 cubes, only available in the Z06) makes 505hp/470 tq, and this is significantly better.

I am sure that this new 426 ’Elephant’ Hemi V8 engine is for those who wants high power but with the passiveness of a stock car.

  (340) posted on 12.16.2010

Technology marches backwards with heavy cars and V8s; F1 is getting more power from a sub 2liter four cylinder turbo. But if you like "heavy iron" this is about as good as it gets.

Id bet my house this is gonna be in the next Srt-8 Charger and Challenger... Hell, maybe even the Ram too!

I think HEMI will be in future because it offers great performance for dragracing.

Every time I hear about a Hemi engine I cannot help of thinking about the day when they will understand that this giant engines life will soon be over and they need to start building fuel efficient engines, maybe electric ones!

Indeed, some nice, cheap but awesome engine!

That block engine I could take home and use it as a statue! It’s a piece of art!

  (807) posted on 12.14.2010

wow I wonder how much horses do this baby could have when paired with a high speed transmission and perfect ratio.

  (806) posted on 12.14.2010

now that was impressive, I bet this new engine will be the new Icon parts for the muscle cars.
