“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.”
This isn’t the 350 that your neighbor pulled out of a C10 truck and slapped a hot cam into. No, this is a 110-octane-only race crate engine built exclusively to win races at the local 1320. GM advises that the LSX454R comes with no warranty and is “not for road use”.
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.
Surely you’re aware of the C7 Corvette. You know it’s a huge leap for Corvettes. You know that valets go joyriding in them. You know a manual Z06 did the Nurburgring in 7:13.9, making it the fastest factory Corvette to ever lap that track. You know that with a little fiddling the C7 Z06 can exceed 200 mph. But did you know you can buy the beating heart of a C7 Z06 and put it in any car you want?
Speaking of tires, they do absolutely no good if side to side movement with low pressure causes them to slip off the rim. Being in the middle of nowhere with rubber out of place and no way to change it is an awful situation. However, there are already bead lock rims on the market to prevent this exact problem.
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.
The Kia Sedona can stand toe-to-toe with any of the used minivans on the market. The current models are powered by a 3.3L V6 paired to a smooth shifting six-speed automatic gearbox. The engine has an output of 276 hp and 248 lb-ft of torque. Most owners describe the engine’s acceleration as quick and its response as immediate. The Sedona outshines its competitors by offering a lower price point and more options for every dollar spent.
As if that wasn’t enough, GM then throws on a gargantuan 2.9-liter Whipple supercharger pushing a full 16 PSI of boost. All of that cast iron and forging means strength, and the COPO 350 can set dragstrip records day in and day out without breaking a sweat.
