Dude,
Have a look at those lunatics at the Castlemain Rod Shop.......they create some of the best hot rods in the world.
They've crammed a Packard Merlin into a 55 Chevy. It's been in quite a number of hot rod mags here in Oz. It actually runs, too. It's got a very short driveshaft - about a foot long and as thick as your thigh! Had to move the driver's seat back a fair amount - cooling was also a major headache. It's the kind of machine that's in the "point anad shoot" category. Wouldn't want to mix it up in tight twisty corners.......
There are several pretty good photos of the beast on their website - have a look at the following:

These guys do some world class work.
Cheers
