Even if you can overlook the drab exterior, the cheap plastic interior of this used minivan can almost turn your stomach. Once inside, you will find average passenger space and less-than-stellar cargo space. These things could be overlooked if the Grand Caravan offered a smooth and quiet ride, but it doesn’t offer either.
It’s worth mentioning the base LS9 crate engine costs $17,322, but GM makes the best controller kit ($1601.27), and the LS9 requires external oil and coolant tanks. You won’t get too far without those, bringing the operational total to the eye-watering figure you see above.
In reality, the roomy interior is full of odd shaped materials and cheap plastics that can easily turn anyone off. Oddly, as you move up the trim lines the Sienna loses ride and handling quality. The Sienna’s second row of seating does move quite a distance on its slide mechanisms, but the seats are quite difficult to remove if you want them out of the way for added cargo space.
The beauty of a crate engine is that it can go into any vehicle you want. The engine gave out in your truck? Maybe it’s time for an upgrade. Want to make a V8 Pinto? Go right ahead.
If any car was worthy of carrying the original ZR1’s torch, it was that one. The numbers are huge: 638 horsepower and 604 lb-ft, with 90% of peak torque available from 2600 to 6000 rpm. Translation: lots of power on tap, whenever you want it.
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.
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.
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)
