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.
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?
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.
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.
