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.
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.
Put it all together and you have the monstrous mill that propelled the 2009 ZR1 to 60mph in 3.2 seconds, 100 in 7 seconds, and covered the quarter mile in 11.3 at 131 mph. Keep in mind this isn’t the spec list for a 2013 Gallardo, this was a 2009 Chevrolet Corvette. An all-aluminum supercharged V8 in a 200-mph American car that was faster than a GT-R, in 2009.
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.
Beyond having Chrysler underpinnings that will be serviced by Volkswagen certified mechanics, you get a rebadge that is even worse than the original. The nicest thing that can be said about the Town & Country is that it offers Stow ‘n Go seating and great seating versatility. VW somehow managed to keep the system, but eliminate the versatility.
The Baja had a paint scheme that matched Stroppe’s racing trucks and was fitted with Gates Commando tires, quick ratio power steering, a roll bar, as well as a padded steering wheel. A 302-cid V-8 was dropped in with a C4 automatic transmission transferring the power to wheels.
Having an outdated design alone does not land the Nissan Quest on our list of the worst used minivans, though. The main drawback to the Quest is its interior. First up, the Quest can only seat a maximum of seven when many of its competitors can handle eight.
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.
