The name “Highboy” was not an official Ford term but a nickname given to it by enthusiasts. The 1977.5 models featured a negative arch leaf spring, which dropped the height by 4 inches leading to the “Highboy” nickname for the pre 1977.5 models and the post 1977.5 models being called “Lowboys”.
The modern equivalent of that engine is GM’s ZZ427 crate motor. It stays true to the cast-iron block of its forefather, but runs pump-gas-friendly 10.0:1 compression, sports aluminum heads and an all-forged rotating assembly.
In reality, the roomy interior is full of odd shaped materials and cheap plastics that can easily turn anyone off. Oddly, as you move up the trim lines the Sienna loses ride and handling quality. The Sienna’s second row of seating does move quite a distance on its slide mechanisms, but the seats are quite difficult to remove if you want them out of the way for added cargo space.
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.
Forged steel rods. Forged steel crank. Forged aluminum pistons. Aluminum heads. Mechanical roller cam. Huge valves. A 7100 rpm redline. A massive 13.1:1 compression ratio that’s well into diesel territory. It all combines to make 776 horsepower, 649 lb-ft, and a whole lot of noise from its 7.4 liters of absolute fury. I’ll let GM explain what that all means.
This baby has aluminum heads and pistons, titanium valves, forged rods, and even an aluminum block, for God’s sake. That’s real supercar stuff, but it runs on pump gas. And might I remind you it comes with a warranty. What more do you want?
With so many used minivans on the North American market today, we decided to narrow our list to the used minivans that should have an average retail value between $6,000 and $15,000 according to KBB.com and nadaguides.com. Our assessment of the quality of these used minivans is based on information from Consumer Reports, owner reviews, and professional reviews.
Enter the LT4 crate engine. Power comes on fast: a 1.7-liter Eaton supercharger spins at 20,000 rpm to force 9 pounds of boost into this 6.2-liter engine. That results in the same 650 horsepower and 650 torques you’ll find in the Z06 that’s sitting over at your local dealership, but for a fraction of the price.
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.
Ford’s Special Vehicles Team (SVT) went to work on the 5.8-liter small block V-8 and managed to squeeze 240 horsepower out of it. A lowered suspension, new shocks, anti-roll bars and 17-inch tires put that power to the road and made the Lighting a great handling truck in addition to being a speed demon. The Lightning cranked up to 60 mph in 7.2 seconds and blazed through the quarter mile in 15.6 seconds. The biggest complaint about the Lightning was that it gulped down gasoline.
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 also favors a hydraulic roller camshaft instead of the original’s flat-tappet cam. It makes a few extra ponies over the old model, too: 480 horsepower and 490 lb-ft of torque will melt any tires this engine’s hooked up to.
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?
