How To ‘Nuke A 68RFE

They’re known for their worrisomely high failure rate (even in “built” form), but splitting a 68RFE case in half is a new one to us. Gillette, Wyoming’s Unique Performance took delivery of a very ill Ram and removed this exploded slushbox in pieces. We’re guessing a driveline issue was the culprit rather than the torquey 6.7L Cummins parked in front of it. Regardless, the only real salvageable component was the converter. Moral of the story: don’t ignore driveline vibrations…they can end up biting you.

Kill Devil Diesel’s Boss 429

On the cutting edge of 6.0L and 6.4L Power Stroke performance over the past several years, Kill Devil Diesel recently pieced together a wild 6.4L-based build. Intended to do lots of damage on the pulling track, the big bore 429 ci the folks at KDD are referring to as their Boss 429 sports an internally balanced crankshaft, Wagler rods, and forged and coated Mahle Motorsport pistons inside a PSP dry block. A full Jesel valvetrain is employed to withstand the high rpm and extreme duty the 7.0L V-8 will see. With the hashtag #2000hporbust associated with it, this 6.4L-based power plant should be pretty serious.

Harsher Emission Standards May Be On The Way…

Trump-era environmental policies continue to be undone, and the U.S. EPA recently issued a notice of reconsideration for its 2019 decision to withdraw the Clean Air Act preemption waiver for California greenhouse gas emissions and zero emission vehicle programs. If finalized, the action will restore the state’s ability to issue and enforce its own greenhouse gas and fuel economy regulations, which would also mean that other states could adopt California’s more stringent GHG emission standards. The EPA will be accepting public comments and concerns on the notice of reconsideration until July 6.
