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.
The price gap between a complete C7 Z06 and its engine says a lot about what it takes to make a car perform that well. On that note, it’s worth mentioning that all of the engines from this point forward are absolutely insane. They’re bonkers. They’re nuts. They have no business going into any car that isn’t equally advanced in the suspension, chassis, and safety departments. If you so much as look at them the wrong way, you should probably see a doctor. Here we go.
We will give you specific information as to why these are the worst used minivans to buy, so that you can decide whether you agree with us or not. Also, our list is in no particular order, so Number 1 is not necessarily the worst used minivan in the world, just the first unit that came to our attention.
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.
“Quite simply, the LSX454R drag racing engine is the most powerful GM crate engine ever from Chevrolet Performance and it’s designed to do one thing: help you win races with great durability.” “Engineers simulated 600 back-to-back drag strip passes on the engine dyno, ensuring it would stand up to years of performance without the need for major maintenance, round after round, season after season.”
We do have to point out that the Sedona offers less cargo space than several of the used minivans on the list and does not offer removable second-row seating on any trim level. Those shortcomings are overcome in our minds by the generous warranty, low sticker price, and long-term durability of the Kia Sedona.
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:
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.
