click above for more high-res iamges of the V8-powered Scion xB

Forget about body kits, custom fiberglass enclosures for your woofer and LCDs in the headrests. This is the only way to make the Scion xB entertaining in our humble opinion. Oh yeah, Scion wants you to think its cars are more fun than a box of rocks, but like Flava Flav said, don't believe the hype. We'll even forgive the fact that there's a big, dumb carburetor sitting atop the Chevy-based small block. This first-generation xB is owned by a guy named Rick, who apparently knows his way around plasma cutters, nibblers and welders. It's not quite finished yet, as evidenced by the photos showing a stripped interior and lots of zip ties, but Rick's Scion is already quite the sleeper.

Peering inside the engine bay, it's the tidy dimensions of the small block FTW. A transmission hump/center tunnel had to be added, and the chassis was converted to rear-wheel drive, too. Keep in mind, this is the smaller, original xB. The overinflated second-generation would have even more space in the engine room for this sort of chicanery. There's obviously some time and money spent to give this ho-hum little box a big infusion of epic cool, and we bet that's all worth it when you can take in the looks of discongruity as you blow the doors off the unsuspecting.

Festiva, mid-mounted V8 – okay, we're with you. Front wheel drive? Uh, sounds like a fine way to blow a lot of dollars adapting components in order to send the power to the wrong pair of 13-inch tires. No Festiva conversion will ever top the SHOgun, which planted the Taurus SHO's Yamaha V6 where the rear seat used to be in the diminutive Kia derivative. CarDomain member TheOne-Originals has exceeded the SHOgun's cylinder count by squeezing a small-block Chevy V8 behind the front seats. The power runs forward, with a Turbo Hydramatic transmission coupled to a BMW limited slip differential. Customized Audi driveshafts are responsible for transmitting torque to the teeny tiny tires.

We like the exhaust stacks that stick through the roof, as well as the Mad-Max patina the whole project wears. The SHOgun may have been more finely finished, but this car wouldn't have a problem drawing at least as large a crowd. It might not be tremendously amusing in a torrential downpour, but being able to crack that four-barrel open and instantly boil the front tires has its own charm. Our favorite quote from the car's description? "The stock brakes definitely need upgrading, but I'll get to that later." Or not. The car might kill its builder first. We can only imagine how evil the torque steer might be, and mid-engined cars are notorious for being wicked near their moment of polar inertia. A sleeper econobox with twice the cylinder count with which it came, mercenary unmuffled exhaust, and the pending addition of a flamethrower system for the exhaust? Yeah, that would definitely entertain us.

Thanks for the tip, Rob!

There are some misguided folks out there who think that big displacement and technology are somehow mutually exclusive. And then there's Tom Nelson of Nelson Racing Engines. His Project F Bomb engine (a twin-turbo 408 cubic inch small-block Chevy that threw down an evil 1480 HP and 1440 lb-ft) recently graced the cover of Hot Rod magazine, and he has plenty of other fine examples showing his ability to build huge power via forced induction.

The video above shows what happens when 522 cubes of big-block Chevy are subjected to 10 PSI or so of boost and stuffed into a classic Pontiac LeMans. We're going to warn our readers that a bit of rowdy driving occurs past the half-way point, so if you're easy upset by hot-testing a rev limiter on public streets, it's probably best to skip to the next post. On the other hand, if you want to see what happens when 1000 HP is applied in 3rd gear at 20 MPH, by all means roll the clip and prepare to receive some goose bumps. Polite words fail to accurately describe such a diabolic creation. Note, too, just how mild mannered this thing is when driving at sane speeds.

Of course, the best feature about such a setup is its adjustability. It can be knocked down to a mere 1000 HP or so for taking trips to the grocery store on pump gas, and then cranked up towards 2000 HP on racing fuel - if, indeed, the rest of your car (and your guardian angel) can handle that sort of power.

Call it what you will - "Blue Devil", "Corvette SS", or just "#%$&ing fast" - but even though we don't yet know the moniker of the upcoming ÜberVette, a clearer picture is being painted of the 650-hp supercharged lump that should propel it past most of the supercar elite. A sharp-eyed and well-connected member of the Digital Corvettes forum managed to have a camera in the right place at the right time, and grabbed three shots of the blown GenIV V8 that is said to carry the SPID designation of LS9.

Most notable is the blower setup, which puts the compressor down low in the valley, with the blower drive snout sneaking past the front-mounted throttle body. Air flows upwards through an air-to-water intercooler (note the yellow caps on the coolant fittings at the rear of the IC), and then drops straight down into the intake ports. The arrangement is similar to that of Cadillac's supercharged Northstar, but this engine appears to be significantly more compact despite providing 40% more output. There's also a bit of bling in the form of valve covers and a intercooler housing formed from polished aluminum, which is certainly more fitting to a $100K vehicle than the usual plastic or stamped steel.

Speaking of GM's luxury brand, rumor has it that a lower-output version of this engine will make its way into the Escalade. That would seem to contradict Caddy's claim that there will be no V-series SUVs.

Is it too early to start wondering when this will be available as a crate motor?

General Motors announced that it will be introducing 19 -- yes, 19 -- new engines and powertrains for the 2007 model year. The powerplants span the gamut of technologies available today and include hybrids, traditional gasoline-powered engines, ethanol powerplants and everything in between. The claim to fame for every last one is better fuel economy, reduced emissions and more choice, the automaker says.

The offerings include a small-block V8 for trucks, six-speed automatic transmissions and powertrains employing GM's Active Fuel Management technology.

Both General Motors and Ford are making big inroads into the aftermarket world for high-performance parts, and now GM Performance Parts is taking it to the streets-- literally. The company has put together a mobile exhibit of its offerings called the GM Performance Parts Power Shop, which is travelling the country this summer making appearances at various racing and car-oriented events.

One of the stars of the exhibit is a fully-operational display of the GMPP ZZ572 big-block crate engine - 720 hp of off-the-shelf motivation. The drag racing and hot rod-oriented display also features a brand-new drag racing simulator that promises the "full sensory experience of rocketing down the quarter-mile."

The Power Shop debuted this past weekend at "The Year One Experience" at Road Atlanta in Braselton, Georgia.
