I’m a big fan of classic straight-six engines. So I was excited to find out that stellantisThe V8’s replacement is an inline-six (I6) called the Hurricane. Get this: It uses two turbochargers to make over 500 horsepower from just 3.0 liters of displacement. Stellantis then announced that it would offer this engine to hot-rodders as the “Hurricante”. Oh the possibilities! Obviously you could swap this compact and powerful engine in many vehicles. But here are four multi-make classics from Stellantis that had a factory I6, each of which would make a very cool Hurricate engine swap project.
Jeep Cherokee XJ

One of the most beloved I6 engines of all time was the powerful, naturally aspirated 4.0-liter engine found in Jeeps from 1986 to 2006. Because the first Stellantis vehicle to offer the new Hurricane I6 is Jeep’s Wagoneer , it would be very appropriate to trade in a Hurricane for an older Jeep SUV. I think a Cherokee with some manual transmission would be the coolest combination, but that’s just my preference. The 4.0 weighed in at 483 pounds and made 190 horsepower. Making over 500 horsepower at 441 pounds, the Hurricrate would be a major engine swap upgrade.

My first car was a 1964 Dodge Dart. Its trusty “Slant 6” engine is solely to blame for my I6 obsession. This bulletproof I6 was the base engine for nearly all Chrysler Corporation vehicles made during the 1960s, 1970s and early 1980s. This led to some reliable but underpowered pickup trucks. I’ll bet you bucks on the donuts Ram offers the Hurricane I6 in its next generation of half-ton trucks. If you were to trade a Hurricrate engine for an old Dodge Slant 6 truck, it would have one of the quickest shifters around, and all of its components would still be from the great Stellantis family.
Alfa Romeo 2600 Sprint

Guess who else is in the Stellantis family: Alfa Romeo. Like Aston Martin and Mercedes-Benz, this Italian automaker built some incredible I6 engines for its first grand tourer cars. One of their last I6 cars was the 2600 from 1962-1968. The 2600 Sprint was a muscle coupe variation that, unlike the Spider convertible, can still be had for under $50k. You maybe even be able to find one without a motor. Obviously, changing a Hurricrate truck engine under the hood would require a ton of modifications. But where there is a welder, there is a way. Alternatively, you could split a Maserati 3500 GTI from the same era and make all sorts of enemies among Italian car purists.
Chrysler Stout Charger
This one is even more niche, but stay with me! Australia placed an advance tax on V8 engines, so Detroit automakers built some high-powered I6 muscle cars for export. One of the best of all is the Chrysler Valiant Charger. Although its name sounds like Mopar Mad-Libs, it is one of the most gnarly muscle cars of all time. It was mounted on an A-body chassis (think Dodge Dart Demon-sized) with a factory widebody kit. One engine option was an I6 with a “Six Pack” carburetor upgrade making 302 horsepower, setting a six-cylinder record. Imagine swapping out a Hurricrate engine to boost this unique loader to over 500 horsepower.
