When you take your Jeep off-road, you may end up in situations where the body is going to take a hit. Hard knocks from rocks and boulders can pound dents and tears into your body in no time. The way around this with Jeep mods is to armor up and protect your vehicle from punishment.
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.
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.
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?
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.
They’re even saying it will beat the old ZR1’s Nurburgring lap by a full 20 seconds. And if the current GM Performance Catalog is any indicator, in a few short years you’ll be able to stuff either one of those engines into your grandma’s old woody wagon. What a time to be alive
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.
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.
It also takes more torque to get oversized wheels turning which saps overall output and drains the gas tank much faster than normal. Swapping to lower gears and increasing the number in your gear ratio may be enough to offset the difference. A notable exception here is diesels, which sometimes put out so much torque that the difference with larger wheels isn’t noticeable.
Surely you’re aware of the C7 Corvette. You know it’s a huge leap for Corvettes. You know that valets go joyriding in them. You know a manual Z06 did the Nurburgring in 7:13.9, making it the fastest factory Corvette to ever lap that track. You know that with a little fiddling the C7 Z06 can exceed 200 mph. But did you know you can buy the beating heart of a C7 Z06 and put it in any car you want?
The Chrysler Town & Country is basically a rebadged Dodge Grand Caravan with some added tech and comfort. Even in its lowest trim level, the Town & Country offers more refinement than a Dodge Grand Caravan. Still, as used minivans go, there are better models on the market today.
That’s right, in the GM Performance Catalog of crate engines an 8-liter V8 is considered “small”. With max revs set at just 4500rpm, the Vortec 488 is a mill designed not to power the car you’re racing, but the truck you’re hauling it with. With 375 horsepower and 475 lb-feet of torque on tap at only 3200rpm, the 488 can tow that high-dollar enclosed trailer without breaking a sweat. Or it could pull your boat, your cattle, your neighbor’s house, or the grandstands at your local dragstrip. You get the idea.
It almost goes without saying but the weight allowance should give more than enough to haul your vehicle up or out. As a general rule of thumb, the winch should be rated for a minimum of 1.5 times the gross vehicle weight.
