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:
Tires are arguably the most important part of the Jeep mods you’ll want to consider before going off-road. If they’re too small, they make the vehicle look silly and performance just won’t be there. If they are too large, there will be clearance issues on flat surfaces as well as rubbing while turning.
The Dodge Grand Caravan has been one of the top selling minivans since it was introduced for the 1984 model year. The Grand Caravan is so popular that more than 11 million units have been sold globally, with several million units having been sold in North America alone. With so many new units sold, you would assume that the Dodge Grand Caravan would be on a list of great used minivans. You would be wrong.
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.
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.
This is the beginning of the pickup truck era for Ford, and while not the most exciting choice on our cool old ford trucks list, it was one of the first mass-produced trucks out there and helped build the foundation of the truck market we know today.
Rock sliders create a solid barrier between your Jeep and a hard surface. Meanwhile, replacing stock bumpers with steel fabricated off-road bumpers protects the front and rear from sharp slams. These can also give a greater angle of approach when going up slopes or coming down from them.
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?
