We�re pretty sure that, during the time Aston Martin was under the ownership of Ford, the thought of stuffing an exotic V12 powerplant under the bonnet of a Mustang must have crossed the mind of a few company engineers. 
And while we never saw something of the sort officially from Ford, an independent custom shop actually realized the idea with the 2005 Ford Mustang 'Vanquishd' show car that was presented at the 2006 SEMA aftermarket gathering. Built by Western Motorsports, this one-of-a-kind Mustang gets a 6.0-liter V12 engine with 600 ponies from a 2001 Aston Martin Vanquish. Power is sent to the chunky rear wheels through a 6 speed manual Tremec T-56 transmission.
Much like Christine in the Stephen King novel of the same name, this 1957 Triumph TR3 Special began life as nothing more than a�car. Since then it�s mutated into this thing that sports a faux-Ferrari body and a Chevy 350 V8 under the hood.
Two observations: one, there�s nothing cooler than a LS1-engined BMW that is externally indistinguishable from its bread-and-butter cousins and two, the Apple iPhone is probably the worst thing for filming a movie ever. A little less of number two and a little more number one, if you please. 
This BMW E46 3-Series coupe, or as its UK owner has appropriately named it, the 357Ci, started its life as a 2001 325Ci with an M Sport Package. In the hands of its current owner, it received the same 5.7-liter LS1 V8 engine as the rather forlorn looking Porsche 911 we wrote about last week, making this the second American-powered German automobile we�ve featured in as many days.
In the late �90s, Australian John Bettini unleashed onto the word the Bullet Roadster. What begin life as a heavily modified Mazda MX-5 with an RX-7 13B powerplant gradually evolved into a V8-engined monster like the one you see here that we found for sale in Queensland, Australia. 
According to the seller, this was the fifth Bullet Roadster built and the first V8-engined one to roll out of the company�s then new Chinderah, NSW factory. It�s all hearsay, of course, but I�m willing to believe the words of a 62yo motoring enthusiast with arthritic knees. So here goes...Bullet No. 5 was a special order from a man named George Covacic who supplied a 4.6-liter all-alloy, fuel injected V8 crate motor along with a Tremac 5-speed manual transmission and the differential from a Holden Commodore SS. Like all Bullet supercars, the brakes and suspension came from the Mazda RX-7.
By taking a kitbashed GM-sourced LS1 V8 engine and slotting it into an AWD Porsche 996, LS1tech forum member �1dirtyZ� has set out to create something truly unique. Sure, it�s unconventional and perhaps a little sacrilegious...but just look at the Porsche donor car. 
It�s a wreck, the victim of a catastrophic engine fire. It has a ruined interior and a body that�s been damaged both by fire and rust. It would have spent the rest its days rotting away in a car wreckers yard if 1dirtyZ had not rescued it.And even though this confabulation of All-American grunt and German precision engineering is not yet finished (it doesn�t have a rear bumper, for one), it certainly runs and can even be driven around a dirt race track. You can check out our gallery of in-progress images below and a handful of videos showing the V8-powered Porsche 911 running.
