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.
This is why you should be equipped with recovery gear. Tow and/or ratchet straps can come in handy in countless ways and you should always have a full size spare. These also stow away easily so they don’t take up much space or make a mess of your interior. When it comes to changing that spare, you may also have to look at a jack that can overcome your increased ride height.
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.
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.
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.
On paper, the Toyota Sienna seems to offer everything. It is roomy and has plenty of cargo space. Unfortunately, what looks good on paper isn’t always good in real life.
In addition to their beauty, they were pretty powerful for their day. In 1954, Ford dropped in an overhead valve V-8 that put out 130 horsepower. By 1956, it was up to almost 180. In addition, 1953 was the first year that an automatic transmission was put into a Ford pickup.
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.
There’s nothing like a quick and dirty slapdash lift job with some pucks to get the lifted look. However, this won’t hold up when push comes to shove on choppy surfaces or hard slopes. You will need suspension travel as well as flexibility and rigidness at the right times. When starting your Jeep mods, hard plastic pucks won’t give you the response and dependability you need.
That didn’t stop this shop from stuffing the lower-compression street version into a 2012 GMC Sierra single cab truck, a vehicle which, as you may know, has almost no weight over the rear wheels. That must be a hoot to drive.
We will never understand why this isn’t always a default option on all new vehicles capable of off-road driving. There are times when you will need slow and steady power coming from both wheels on each axle. A limited slip differential will keep some of the single side spin down but a full locker is much better in terms of 4×4 Jeep mods. Locking both wheels to spin in unison is an easier way to get out of sticky situations. When combined with the use of a properly anchored winch, there’s almost nowhere you can’t go.
In fact, at highway speeds, the Grand Caravan is one of the noisiest used minivans around. The engine and transmission noise in the cabin can drive you insane if you ride long enough. When you throw in the wind and road noise that join the cacophony, you can see why this used minivan should never leave town.
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.
