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.

Dodge Viper plant will close for good Aug. 31

It has been a long time coming, an end rumored since at least 2015, but after 25 years, the Dodge Viper's demise is nigh. Production of the $90,000 bespoke sports car is ending. Therefore, FCA will be shutting down its Conner Assembly Plant on Aug. 31. Automotive News reports that the Detroit plant will be shutting down. The car has been hand-built there since 1995, save for a hiatus in 2010-13 (production began at FCA's Mack Plant in 1992). The Prowler was built there, too, from 1997 to 2002. More than 80 workers currently build the Viper, making Conner FCA's smallest assembly facility. But not many Vipers are sold - 630 last year - despite an enthusiastic following. And of course FCA's own 707-horsepower Dodge Challenger and Charger SRT Hellcats and new 840-horsepower Challenger SRT Demon can't help matters. But the last straw is the fact the Viper can't comply with new safety requirements going into effect. On the bright side, the UAW has seen the plant closure coming since 2015, and FCA has told the state of Michigan that it expects to find positions at other plants for the Viper crew. FCA has been celebrating the Viper valedictory for a couple of years now, offering serialized special editions, including the $121,000 Viper ACR, and touting the ability to build unique Vipers with its "1 of 1" customization program, with a choice of 16,000 unique paint colors and 48,000 unique stripe combinations.

A look at the Dodge Demon's drag settings, modes, and go-fast tech

In the same video that gave us a peek at the 2018 Dodge Challenger SRT Demon's performance stats, there's a serious dump of info on the tech and tools that will likely help this muscle coupe slaughter drag strips. Dodge has outlined a few of them for us and we're using the power of inference to figure out the rest. Here's what we've gathered. A lot of these hints come from the Demon's version of Performance Pages, the infotainment screens that show what SRT models are doing and let the driver change the powertrain and chassis setup. There are a lot of Demon-only features, including line lock, a quick cooldown mode for the supercharged engine, and data recording. And of course there are pages to show a digital time slip with acceleration and braking figures, a g-load plot, and lots of gauges to track temps and levels. The engine output is shown in the video on a special Dyno page. It tracks horsepower and torque over time on the upper graph, and engine rpm and shift points on the lower graph. And we think it's still hiding something. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Any good drag car has a line lock, allowing the driver to lock the front brakes and leave the rears free to do a nice tire-warming (or tire-shredding, depending on length) burnout. Ford has it on the Mustang, Chevy puts it on the ZL1, and now Dodge is adding it to the Demon. It should help get the giant Nitto tires up to temp for a drag run. And once the tires are warm, there's launch control, just like on the SRT Hellcat, with selectable rpm to dial things in for the conditions. The Demon also has a shift light in the cluster, and the driver can set a shift point individually for each gear. After each drag run, you can activate Quick Cooldown, which Dodge says uses the first production application of After-Run Chiller – it runs the cooling fan and intercooler coolant pump with the engine off until the coolant reaches its target temp. It's shown in one of the slides above. The checklist on the left side of that page suggests it requires a set of conditions be met to work: engine off, hood open, and sufficient battery level. This further reinforces our theory that the supercharger is going to make big boost, beyond the Hellcat's 11.6 psi. And while you're waiting for the supercharger to cool off for another run, you can review the performance data the car records.
