Then again, you could always go with the "dare to be different" route that my buddy did with his 64 dart, and see what kind of power you can get out of the ole leaning tower of power. Clifford offers 4bbl intakes and a header for the slant.
A couple of years ago, I saw a slant on ebay that was bored and stroked to 340ci.

But still, you just can't beat that V8 sound and torque......

So, a truck mount on the passenger side, and a normal mount on the driver's? That combo work with /6 to 360 swap as well? Save me some headaches with my 70 dart if it works.
