That thing got a Hemi? Mopar engine kits make it easier to say yes

Thanks to a new kit from Mopar, classic car owners will have an easier time dropping Hemis into their muscle cars. The kit works with Mopar's 345 and 392 Hemi engines (5.7 and 6.4 liters respectively) and with cars built before 1975. The kit will run $1,795 and has everything needed to get one of the above engines running. The parts include a power distribution system, engine computer, engine and chassis wiring harnesses, O2 and intake air temperature sensors, ground wiring and a gas pedal. The kit is also designed to work with a manual transmission, but Mopar says a transmission such as the Torqueflite 727 and 904 can be made to work with the system. As for examples of the kit in action, take a look at the Jeep CJ66 and Dodge Challenger Shakedown that Mopar revealed this week at the SEMA show. Mopar also offers a few other parts to help complete the project, including various oil pans to clear subframes, a set of headers, and accessory drives for power steering and air conditioning. All of these parts are extra cost though. You'll also need an engine, and the 345 starts at $6,070, and the 392 runs $9,335. However, if you happen to already have one from 2014 or newer, that will work, too. Muscle car fans are getting more choices for their engine conversions. Chevrolet Performance already sells crate engines with "Connect and Cruise" kits to get its engines working in classic cars. The General also offers it with more engines. However, for people who want to keep a Mopar engine in their classic Chrysler, Dodge, Plymouth, or Jeep, this is a cool new option.

2015 Dodge Viper getting small increase in power

The Viper is used to being the most powerful car in the Dodge and SRT stables, but the arrival of the 2015 Dodge Challenger SRT Hellcat means that's no longer the case. The serpentine supercar is, however, reportedly getting a small boost in output for 2015, amounting to all of five horsepower.
The increase was uncovered by Road & Track courtesy of the SAE J1349 certification process to which Detroit's Big Three automakers submit themselves and which reports the Viper's output at 645 hp instead of the 640 it was rated at until now. There are a hundred factors that could have contributed to the relatively mild boost in output (best guess? nothing at all changed...), but we doubt anyone's going to complain about some extra horses under the hood.
The five-horsepower boost brings the Viper that much closer to the 650-hp Chevy Corvette Z06, not to mention the 707-hp Hellcat, but the Viper's impressive power-to-weight ratio ought to mean it'll have little problem keeping up in a straight line - which is just one of the reasons why Chrysler won't shoe-horn the Hellcat into the Viper: as R&T points out, the supercharged engine is too heavy and the blower makes it too tall to fit in the Viper's engine bay.

The Dodge Demon gets a Drag Mode and a lesson in Newtonian physics

It's Thursday morning, which means we have more news on the upcoming Dodge Demon, the pumped-up Challenger Hellcat variant that's looking to cause mayhem at a drag strip near you. This week's video, "Third Law," shows the Demon's revised suspension in action and displays another one of SRT's cryptic messages. Dodge claims that the 6.2-liter supercharged Hemi V8 in the Hellcat twins is compromised because it's fitted to a car that needs to be comfortable on the street in addition to a performer on the drag strip. Not so with the Demon, as Dodge says the car is "designed to be highly competent in all drive modes and configurations," including the all-new Drag Mode. Dodge says details about the new mode will trickle out over the next few weeks, but all the info this week focused on suspension. The "Third Law" in this week's title refers to Isaac Newton and motion: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." We're not sure what Newton would have thought seeing the sidewall wrinkling Nitto NT05R drag radials in action, but he'd probably have a reaction of some sort himself. An ideal suspension setup for the drag strip makes for a poor setup on the road. As Dodge puts it, the "old school" way to set up a drag car was to "get the quickest reacting springs upfront, the softest rebound front shocks that wouldn't restrict the springs' reaction, remove any restrictions (sway bar) and increase the compression of the rear shocks." This would give a car great front to rear weight transfer but made for very poor lateral direction control, meaning minor corrections were difficult. The Demon's Drag Mode will use electronics to give the car the best combination of launch and lateral stability. Dodge listed some of the parts to help aid in this goal. They also gave us a few equations that we can't make sense of. Let us know if you have any clues.
