It’s not that we’re going in cost order here, the LS9 crate engine ranks near the top because of its insane rarity. According to GM they aren’t building any new ones, they’re just selling the leftovers from the 2009-2013 Corvette ZR1. You know, the first Corvette to ever exceed 200 miles per hour. The one that lapped the Nurburgring four seconds faster than a Nissan GT-R way back in 2009. Nevermind that this happened nearly a decade ago the 6.2-liter LS9 is still insane today.
While these aren’t necessarily Jeep mods, they should be checked and double checked when you’re putting in work. No matter how careful of a driver you are, there are likely going to be times when you get yourself into a bind. Even if it never happens to you, others who you come across or go adventuring with may need help.
Another party trick of the 488 is its ability to run on compressed natural gas (CNG) or liquefied petroleum (LPG) in addition to regular pump gasoline. That’s thanks to the stainless valves and hardened valve seats. A forged crank, rods, pistons, full-length cooling jackets, and cast-iron head and block ensure maximum durability and longevity even in high-stress situations. Just add your choice of intake manifold, carb, and all the regular bolt-ons we talked about earlier, and you’re good to go.
Across North American, used minivans have become a ubiquitous tool for busy parents, small delivery companies, and school systems. We say used minivans because of the rising cost of buying a new vehicle of any kind. Because of their utility and generally well appointed interiors, the minivan class seems to be increasing in cost faster than many other car groups. That leaves savvy buyers looking for used minivans in larger numbers.
With the Town & Country, Chrysler did not go far enough to eliminate the noise and ride quality issues found in the Grand Caravan. To further exacerbate these issues, the Town & Country is a fairly expensive used minivan. The most recent versions of the Town & Country are powered by the same 3.6L V6 that you will find in the Grand Caravan. The engine offers the same 283 ponies and 260 lb-ft of torque. Chrysler didn’t even bother to tweak the fuel economy.
Having an outdated design alone does not land the Nissan Quest on our list of the worst used minivans, though. The main drawback to the Quest is its interior. First up, the Quest can only seat a maximum of seven when many of its competitors can handle eight.
This crate engine is hand-assembled in its own special facility, presumably so as to not risk contamination by one of those plebian engines we saw earlier. Gone are the days of solid lifters and cast-iron heads this beast combines an LSX cast-iron block, LS7/Z06 aluminum heads, forged steel crank and rods, forged aluminum pistons, hydraulic roller cams, and 10.2:1 compression.
Let’s start with the 9.1:1 compression, which means you can run this on pump gas. Add in a cast aluminum block, titanium valves, and a forged steel crank attached to forged titanium rods attached to forged aluminum pistons. Top that off with hydraulic roller cams, aluminum heads, and a high-helix supercharger pushing 10.5psi of boost.
