They mechanically lock the rubber to the rim so that sidewall sag from less than stock psi doesn’t drop the bead and leave you stranded. An added bonus to these is that their distinctive look adds to the curb appeal along with other Jeep mods.
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:
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.
Did you know you can buy a Corvette’s engine without buying the rest of the car? Are you building a project and looking for the best engine to finish it off? Do you want to drool at how much money people spend on engines? Do you want to see some of the best crate engines ever made? You’ve come to the right place.
The Nissan Quest barely survived the 2017 model year and reached the end of its production run after the 2018 model year. There are many reasons the Quest is out; the main one being that Nissan has not updated the oddly designed minivan for several years.
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.
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.
The beauty of a crate engine is that it can go into any vehicle you want. The engine gave out in your truck? Maybe it’s time for an upgrade. Want to make a V8 Pinto? Go right ahead.
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.
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.
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.
The Nite was sort of a half-assed attempt at a special edition. The upgraded features were an upgraded paint and decal job along with some forged aluminum wheels. A blackout trim on top of a black paint job made it stand out and a decal running down the side that transitioned from blue to magenta gave it a menacing look, but that is where the upgrades ended. The suspension was also tightened up but this was hardly a performance pickup.
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”.
