Plus, in the late 60s, Chevy didn’t use engines over 400ci in midsize cars this meant COPOs were far and away the fastest Chevelles and Camaros on the road. From day one they were, and still are, offensively expensive.
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?
“Quite simply, the LSX454R drag racing engine is the most powerful GM crate engine ever from Chevrolet Performance and it’s designed to do one thing: help you win races with great durability.” “Engineers simulated 600 back-to-back drag strip passes on the engine dyno, ensuring it would stand up to years of performance without the need for major maintenance, round after round, season after season.”
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.
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
GM has been producing small-block and big-block engines for decades. Throw a few extra parts on one of these bad boys and you’ll be burning tires in no time. Before we talk about the best GM crate engines, let’s start by answering a few basic questions. Ooh, shiny. (source)
Let’s start with the 9.1:1 compression, which means you can run this on pump gas. Add in a cast aluminum block, titanium valves, and a forged steel crank attached to forged titanium rods attached to forged aluminum pistons. Top that off with hydraulic roller cams, aluminum heads, and a high-helix supercharger pushing 10.5psi of boost.
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.
We do have to point out that the Sedona offers less cargo space than several of the used minivans on the list and does not offer removable second-row seating on any trim level. Those shortcomings are overcome in our minds by the generous warranty, low sticker price, and long-term durability of the Kia Sedona.
This has been but a taste of the vast GM Performance Catalog. GM crate engines run the gamut from affordable and economical four-cylinder mills to gallon-per-mile big blocks that sound like the devil gargling Listerine. And the future is bright: Chevrolet is bringing back the COPO Camaro and the newly-launched 2019 ZR1 packs 755 horsepower and a 210-mph top speed.
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”.
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.
This is why you should be equipped with recovery gear. Tow and/or ratchet straps can come in handy in countless ways and you should always have a full size spare. These also stow away easily so they don’t take up much space or make a mess of your interior. When it comes to changing that spare, you may also have to look at a jack that can overcome your increased ride height.
