Every December, racers and gearheads gather at the Performance Racing Industry (PRI) show, located in sunny Orlando, Florida.

It’s also the perfect opportunity for the automakers and their parts divisions to roll out some serious hardware, in preparation for next year’s racing season. In 2010, Chrysler is pulling out all the stops – it’s Motor Parts division (yes, that’s what MOPAR really stands for), is releasing an all new 426 cubic inch Hemi V8, based on the Generation III series architecture.

This motor sports an aluminum block and heads, comes with a complete oil pan and intake manifold assembly and will retail for $13,675, when production begins later this month. Considering it cranks out a whopping 540-hp and 530 ft-lbs of torque, plus what original factory iron-block 426s go for, that’s a considerable bargain.

Other cool stuff at the PRI Mopar display this year, include a new Challenger Drag Pack car, powered by a 500-plus cubic-inch V10. Already approved for NHRA Stock and Super Stock racing, the first of these limited edition drag only specials will roll off the assembly line next year and promise to make things rather interesting, especially as Ford is about to dish up another Cobra Jet Mustang, likely in time for the 2012 season.

Other cool Mopar stuff  for 2011 includes cold air intake kits, new W2 aluminum cylinder heads for traditional small block V8s (read 340/360 Wedge engines), Gen III Hemi valvetrain tie bars, aluminum blocks, head stud kits and new Challenger rear strut brace kits.

Chrysler has announced it will be bringing four specially-made Mopar vehicles representing each of the company’s brands to the SEMA Show in Las Vegas, including one very special 556-horsepower Challenger designed as a street-legal version of the company’s Drag Pak 1/4 mile racer. Named the Dodge Challenger 1320, after how many feet there are in a 1/4 mile, the car boasts a Mopar 426 cubic-inch, all-aluminum, HEMI V-8 crate engine with the aforementioned 556 horsepower and 540 ft-lbs of torque and uses the stripped-down, race-only chassis that Dodge sells to competitive drag racers.

Other highlights include Mopar police wheels with street-legal Mickey Thompson drag radials, an adjustable coilover kit, six-speed manual transmission with a custom Dynatrac rear housing with Mopar Dana 60 internals, an ARB locking differential and an exhaust bypass system that keeps the car emissions legal on the street but re-routes the exhaust gases past the mufflers for the drag strip.

The car is painted in a non-metallic yellow paint (called Acidic Hue) with matte black graphics. There’s also a new hood, front splitter and new grille panel and headlight surround. As for the inside, there’s all sorts of good stuff, including Dodge Viper seats, a sport steering wheel and Hurst shifter. Much of the other interior amenities, like the center console and radio have been removed to reduce weight and help the Dodge Challenger 1320 deliver maximum performance.

We’ll be sure to bring you more on the car with live coverage of the SEMA Show starting on November 3rd.
