A crate engine or crate motor is a factory-built engine that arrives at your doorstep perfectly timed, balanced, and blueprinted, and ready to provide motive power for any project you have laying around. Included parts are a fully assembled block consisting of crank, rods, and pistons, a fully assembled head consisting of valves, cams, and associated parts, and often a carburetor for fuel delivery.
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)
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.
This Bronco came with a part-time four-wheel drive system and a V-8 under the hood. You could choose from a 5.8L 351M and the 6.6L 400. A C6 automatic transmission came standard or you could pick the optional 4-speed manual. This is the last generation of the Bronco to have a solid front axle, making it great for off-roading.
The Highboy was available with a 360 V-8 or the less powerful six-cylinder. A C6 automatic transmission was a common choice on the Highboy. Its tough look makes these trucks pretty collectible so they can be hard to find and sort of pricey for a fully restored version but if you have the budget, it’s a great choice if you are looking for a cool old ford truck.
The Ranchero is based on a two-door station wagon platform and was marketed as a light pickup that could haul a fair amount of cargo while being easy to operate and drive, like a car. There is not enough space here to cover the various engines and features that were incorporated into the Ranchero over the years, but a few engine choices consisted of a 250 cubic-inch six-cylinder and a variety of V8 power plants that ranged from a standard 302 to a 428 cu-in.

The Routan was designed to offer a firmer suspension for a more fun driving experience. Another fail. When compared to Kia and Honda used minivans, the firmer suspension makes for a clumsier experience all around. These shortcomings put a lot of pressure on the powertrain to offer a glimmer of hope for this used minivan. Nope, nope, nope.
