Plus, in the late 60s, Chevy didn’t use engines over 400ci in midsize cars this meant COPOs were far and away the fastest Chevelles and Camaros on the road. From day one they were, and still are, offensively expensive.
At 9.37 liters, the ZZ572 is the mac daddy of all big block engines. It’s nearly a 1-liter EcoBoost larger than any engine ever fitted to a production vehicle (the 8.4-liter V10 in the dearly departed Dodge Viper). Naturally, that means it’s got loads of power 727 horsepower and 680 torques but those aren’t the most impressive specs.
The Nissan Quest does have the saving grace of being equipped with a fuel efficient engine for the class. The most recent models are all powered by a 3.5L V6 that is capable of 260 hp and 240 lb-ft of torque while delivering 22 mpg on the highway.
Right in line with body armor are more Jeep mods to make sure that the underside is protected. All it takes is one hard drop at the wrong time to snap off an essential part of your vehicle. Skid plates run from simple front and rear protection up to complete chassis coverings. The gas tank and oil pan, as well as the differential and transfer case, are all rather vulnerable spots on the underside. They may be able to take a little abuse but how much are you willing to risk?
One good option the Dodge Grand Caravan has to offer is the Stow ‘n Go second-row seating system that allows you to quickly store the center row of seats for extra cargo space.
GM has been producing small-block and big-block engines for decades. Throw a few extra parts on one of these bad boys and you’ll be burning tires in no time. Before we talk about the best GM crate engines, let’s start by answering a few basic questions. Ooh, shiny. (source)
This may be a no-brainer to some but those who forget this in their Jeep mods often regret it later. There’s nothing like a good winch when it comes to getting yourself out of a sticky situation. Whether you’re stuck in a swampy mud pit or have found a slope you can’t crawl up, these can save the day.
This has been but a taste of the vast GM Performance Catalog. GM crate engines run the gamut from affordable and economical four-cylinder mills to gallon-per-mile big blocks that sound like the devil gargling Listerine. And the future is bright: Chevrolet is bringing back the COPO Camaro and the newly-launched 2019 ZR1 packs 755 horsepower and a 210-mph top speed.
Having an outdated design alone does not land the Nissan Quest on our list of the worst used minivans, though.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.
The Model T lineup was produced from 1908 to 1927 and is famous for being the first truly affordable car. It was an absolute game changer and over 15 million Model T’s were produced. The Model T Runabout Pickup was introduced in 1925 and while it only managed to put out 20 horsepower, the box trunk helped change how cargo was delivered and helped set the standard for future pickups.
It has 113-cc intake ports, 2.25-inch intake valves and 1.88-inch exhaust valves, a massive 1150cfm carb (yes, a carb), a solid-roller cam with 0.714 inches of lift, 12:1 compression, and it requires 110 octane fuel. Here’s GM’s succinct English translation of those stats:
It also offers fewer interior storage areas throughout the cabin, then there is the 25.7 cubic feet of cargo capacity. While nearly 26 cubic feet sounds significant, it is smaller than nearly every other model in the segment.
The Routan was designed to offer a firmer suspension for a more fun driving experience. Another fail. When compared to Kia and Honda used minivans, the firmer suspension makes for a clumsier experience all around. These shortcomings put a lot of pressure on the powertrain to offer a glimmer of hope for this used minivan. Nope, nope, nope.
