Which engine is Cooler?

Thinking outside the box here... you see these 60's custom jobs that had had v8 ' s side by side... now to my idea, how do you put 2 slants side by side???? Lol I'm all about off the wall. I like the poly idea. What about first gen hemi. Another idea is a css/hpp tribute.
dude! I like the idea of two 6's side by side! Especially supercharged!
