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.
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.
At 9.37 liters, the ZZ572 is the mac daddy of all big block engines. It’s nearly a 1-liter EcoBoost larger than any engine ever fitted to a production vehicle (the 8.4-liter V10 in the dearly departed Dodge Viper). Naturally, that means it’s got loads of power 727 horsepower and 680 torques but those aren’t the most impressive specs.
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.
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.
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.
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.
The alternative is to either rebuild an old engine yourself, have an engine builder do it for you, or buy a custom-made engine directly from an engine builder. Each of these options has a fair share of hurdles, and often it’s cheaper to order a crate engine than it is to go those other ways.
The original Bronco was a bit small (it was basically a compact SUV) to compete with the Blazer and Ramcharger in the towing and hauling category so for the second generation, Ford upped its size. This generation of the Bronco was built on an F-150 chassis, giving it more space and, more importantly, more power.
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:
You get the same 3.6L engine found in the Dodge and Chrysler minivans on our list. The only difference is that it is now in a slightly heavier minivan. We couldn’t leave you with a cloud of gloom and doom over the entire world of used minivans. So, here is the best used minivan in our opinion…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.
“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.”
Did you know you can buy a Corvette’s engine without buying the rest of the car? Are you building a project and looking for the best engine to finish it off? Do you want to drool at how much money people spend on engines? Do you want to see some of the best crate engines ever made? You’ve come to the right place.
