We see a lot of them in Jeeps, but honestly, we don't understand why we don't see even more Ram Jet 350s out there. Just hook up a few wires and fuel and you've got one of the easiest injected engine setups out there. besides the ability to run upside down and at angles, the Ram Jet 350 offers insane off-idle torque, awesome top-end power, and razor-sharp throttle response. the engine's 350 hp and 400 lb-ft of torque don't disappoint. And now that the meFI 3 computer controller has been replaced by the meFI 4, closed-loop operation for improved performance through altitude changes is even easier.

When we originally came up with the name for Jp's Project murderous overkill it was because we planned on running a Ram Jet 502 big-block. It's a long story on why we went with an olds 455 instead, but there's no denying this monster's 502 hp and 565 lb-ft of torque, all from an easy-toset- up injected big block. hell, the thing makes over 500 lb-ft at just 2,200 rpm! cappa has admitted to being scared when a Jeep equipped with one just idled past him.

We've been friendly with turn key engine supply for years now and with good reason. the company puts together some really killer, ready-to-run Ls-based engine packages. Although turn key engine supply has packages ranging from 630hp Ls7 and twin turbo 770hp Ls2 setups, we really like the company's 6.0L LQ9 package. the LQ9 package uses a cast iron block, aluminum heads, the truck-type intake manifold, and a performance cam and valve springs to deliver 470 hp and 450 lb-ft. As with all turn key engine supply packages, the 470hp 6.0L LQ9 includes a full harness, computer, fuel pump and filters, front accessory group, air filter, and even engine oil. Just fuel it, wire it, and fire it.

We're not really going to try to narrow down hesco's inline six crate engine offerings to just one because the field is so divided on the subject. Some people just won't give up their trusty 4.0L displacement. others say there's no other way to go than a 4.7L or larger stroker. We're not into debating, but we will say that hesco seems to go the extra mile, whether it's a stock-type 4.0L long block or a fully built and dyno'd 5.0L stroker with hesco's aluminum head (shown). several Jeepspeed guys are winning with their hesco engines, so if they can stand up to the rigors of baja running, your daily commute should be a breeze.

Both making 360 hp and 360 lb-ft, you can pick your poison with either mopar Performance's carbureted or throttle body injected 5.7L crate engines. either comes with a plug-and-play wiring harness, controller, flex plate, production exhaust manifolds, and water pump. You'll need to add the front accessory package (alternator, etc) that fits your chassis. We'd drop one in front of a built Grand Cherokee five-speed auto with a Dodge nP241 t-case and have at the dunes.
