Enter the LT4 crate engine. Power comes on fast: a 1.7-liter Eaton supercharger spins at 20,000 rpm to force 9 pounds of boost into this 6.2-liter engine. That results in the same 650 horsepower and 650 torques you’ll find in the Z06 that’s sitting over at your local dealership, but for a fraction of the price.
The trouble with looking for used minivans; well, any sort of used vehicle, is that you have to do a ton of research to make sure you are getting the best possible buy. Not the best buy in the financial sense of the word, but in the quality of the vehicle that you are buying. That is why we decided to put together a list of the worst used minivans available. We want our readers to have the best information possible when spending a lot of their hard earned cash.
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.
The powerplant behind them was the legendary 427 “L88”, a 450-horsepower 7-liter engine found in many other GM cars including the Corvette. But this version had high compression, required race fuel, and made an insane-for-the-time 450 horsepower.
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:
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.
Yes, you can buy a GM crate engine directly from the factory, one capable of 1200 horsepower, and put it in anything you want. Providing you have enough spare change in your pocket to buy a used Tesla Model S. Oh, and GM is smart enough to not offer a warranty on this one. Sorry Doug Demuro.
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.
It’s worth mentioning the base LS9 crate engine costs $17,322, but GM makes the best controller kit ($1601.27), and the LS9 requires external oil and coolant tanks. You won’t get too far without those, bringing the operational total to the eye-watering figure you see above.
The Ranchero was a big hit with both consumers and automotive critics but is not as popular with collectors as the El Camino, so it is still possible to find a fairly affordable project car. The Nite was Ford’s first attempt at putting a performance special edition pickup out on the streets and while it wasn’t a huge success, it led them to create the Lightning (we talked about this one earlier) a few years later.
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.
With bigger tires and heavier rims on your list of Jeep mods, the stock gear ratio may not be enough to get you where you want to go. This is where changing the gear ratio comes in handy and reduces unreasonable stress on the engine. If the wheels are too tall for the stock gear ratio, there will be a noticeable power drop off from its stock build.
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.
