#LSX

Dodge may drop a 6.4-liter V-8 into a Durango before the current generation model goes away, executives told dealers in Las Vegas this week, several media sources are reporting.

The Durango was last redesigned in 2011, so a SRT version could be a victory lap for the three-row SUV. Jeep may take over three-row crossover duty with its Grand Wagoneer.

If you’re pressed between a Jeep Grand Cherokee Trackhawk or a Durango SRT — there is a third option, this Kia Sorento with an LS engine swap.

Hello Sajeev! Very long time reader, but first time I’ve ever reached out. To start, I happen to be a huge RWD ford fan, (I’m actually helping my best friend put together his 94 mark viii). Now with your interest gained…

Hey Sajeev, I got one for you.

Several engines nowadays are set up to operate on half their cylinders under light-load conditions. Would the design considerations for piston rings vary from those normally used for such cylinders that are only used part-time? The question arises in the context of a 2009 V6 Accord that is currently in the Honda dealer’s shop to have the piston rings replaced at the manufacturer’s expense to cure a continual oil consumption and spark plug fouling problem.

General Motors’ powertrain engineers have undoubtedly demonstrated with the LS family of V8 engines that pushrods still have a place in the 21st century. As successful and popular as the LS has been, I don’t think it’s much of stretch to assume that the new LT1 V8 in the all new seventh generation Corvette will eventually replace the LS engine in its various permutations and applications. The LT1, still a cam in block engine, and still with Ed Cole’s 4.40 inch bore centers, adds direct injection to the Small Block Chevy heritage. The LS family has also been popular as crate motors, used by customizers and high performance enthusiasts as well as with a small industry of companies that specialize in high performance GM products. While you can buy a LS from General Motors with up to 638 horsepower, if that just doesn’t satisfy your need for speed, companies like Callaway, Lingenfelter and Hennessey have shown that the LS engine’s basic architecture is capable of putting out almost twice that power. After talking with Ken Lingenfelter about the new Corvette, I wonder, though, just how tuner-friendly the new LT1 will be.

There’s a new small block in town, baby: keeping the spirit of the original 1949 Kettering OHV V8 alive. Piston Slap says the new name is sad: mediocre memories of the Optispark munching, reverse flow coolin’ LT-1 is not a fitting successor to the sheer splendiferousness that was the LSX. Vellum Venom says that the 2006 Ford F-150 called, asking for its fender emblem back. But what’s the real story?
