Tires are arguably the most important part of the Jeep mods you’ll want to consider before going off-road. If they’re too small, they make the vehicle look silly and performance just won’t be there. If they are too large, there will be clearance issues on flat surfaces as well as rubbing while turning.
Another party trick of the 488 is its ability to run on compressed natural gas (CNG) or liquefied petroleum (LPG) in addition to regular pump gasoline. That’s thanks to the stainless valves and hardened valve seats. A forged crank, rods, pistons, full-length cooling jackets, and cast-iron head and block ensure maximum durability and longevity even in high-stress situations. Just add your choice of intake manifold, carb, and all the regular bolt-ons we talked about earlier, and you’re good to go.
Plus, Chevrolet Performance Crate Engines include a 24-month or 50,000-mile limited warranty. That’s right, most of the GM crate engines you’re about to see carry a factory warranty, so hoon away. These are the big things, but there are many other parts that may or may not be included with your specific crate motor check with your provider for more details.
GM crate engines can usually be ordered through your local GM dealership. You might see online retailers like JEGS or Crate Engine Depot offer these engines, but they’re almost always asking the same price as Chevrolet themselves. We’ve found the Gandrud Auto Group’s GM Performance Motor website is the best resource around. Please note, we are not responsible for large amounts of hours lost while browsing crate engines.
Nevermind what happens when you get bouncing around on choppy trails and crawling across rocky slopes. There’s a fine balance between size, tread, and overall quality that make knowledgeable product reviews a good starting point.
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.
A big block has higher weight and density in the block, as well as larger valve bores, a longer stroke, and a generally larger exterior size. A big block can have the same displacement as a small block, but only the most extreme small blocks encroach on this territory.
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.
