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:
Forged steel rods. Forged steel crank. Forged aluminum pistons. Aluminum heads. Mechanical roller cam. Huge valves. A 7100 rpm redline. A massive 13.1:1 compression ratio that’s well into diesel territory. It all combines to make 776 horsepower, 649 lb-ft, and a whole lot of noise from its 7.4 liters of absolute fury. I’ll let GM explain what that all means.
With so many used minivans on the North American market today, we decided to narrow our list to the used minivans that should have an average retail value between $6,000 and $15,000 according to KBB.com and nadaguides.com. Our assessment of the quality of these used minivans is based on information from Consumer Reports, owner reviews, and professional reviews.
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.

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.
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.
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 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.
