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.
A big block has higher weight and density in the block, as well as larger valve bores, a longer stroke, and a generally larger exterior size. A big block can have the same displacement as a small block, but only the most extreme small blocks encroach on this territory.
As if that wasn’t enough, GM then throws on a gargantuan 2.9-liter Whipple supercharger pushing a full 16 PSI of boost. All of that cast iron and forging means strength, and the COPO 350 can set dragstrip records day in and day out without breaking a sweat.
It’s worth mentioning the base LS9 crate engine costs $17,322, but GM makes the best controller kit ($1601.27), and the LS9 requires external oil and coolant tanks. You won’t get too far without those, bringing the operational total to the eye-watering figure you see above.
Like the old COPOs of the 60s, the 2011-14 models adhered to strict NHRA guidelines. That meant super-small production numbers and a price payable only by professional race teams. It also meant the car’s engine could only make 530 horsepower. But much like the Japanese engine restrictions of the 1990s, that figure seems to have been framed in air quotes. In 2016 a (not extensively) modified 2014 COPO Camaro ran an 8.323-second quarter mile at 165.80 miles per hour. Doing the math, that car was making closer to 1200 horsepower. 1200.
Having an outdated design alone does not land the Nissan Quest on our list of the worst used minivans, though.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.
GM crate engines can usually be ordered through your local GM dealership. You might see online retailers like JEGS or Crate Engine Depot offer these engines, but they’re almost always asking the same price as Chevrolet themselves. We’ve found the Gandrud Auto Group’s GM Performance Motor website is the best resource around. Please note, we are not responsible for large amounts of hours lost while browsing crate engines.
Our list of cool old Ford trucks would certainly not be complete without the Ford Lightning. This performance truck was launched as a response to the Chevy 454 SS and it was not only a looker but cranked out some power as well.
