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.
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.
Remember those COPO Camaros of the 1960s we talked about earlier? The baddest of the bad, the stuff of bedroom posters and “I swear I saw one” stories, the kind of car the uber-rich still build replicas of today? Well in 2011 Chevrolet modified a modern Camaro in a COPO sort of way and took it to SEMA, and the response was overwhelming. So they built it for real. And at its heart, you could have this: a 5.7-liter supercharged 350 crate engine dubbed the COPO 350.
We will give you specific information as to why these are the worst used minivans to buy, so that you can decide whether you agree with us or not. Also, our list is in no particular order, so Number 1 is not necessarily the worst used minivan in the world, just the first unit that came to our attention.
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.
This crate engine is hand-assembled in its own special facility, presumably so as to not risk contamination by one of those plebian engines we saw earlier. Gone are the days of solid lifters and cast-iron heads this beast combines an LSX cast-iron block, LS7/Z06 aluminum heads, forged steel crank and rods, forged aluminum pistons, hydraulic roller cams, and 10.2:1 compression.
The Chevy El Camino is probably the best-known example in this category but the Ranchero was the first and is a pretty cool car/truck. The Ranchero was introduced in 1957 and was in production until 1979. A total of 508,355 units were produced and while we like the early models, they are all pretty sweet.
While these aren’t necessarily Jeep mods, they should be checked and double checked when you’re putting in work. No matter how careful of a driver you are, there are likely going to be times when you get yourself into a bind. Even if it never happens to you, others who you come across or go adventuring with may need help.
