Whats the quickest, easiest and cheapest guaranteed way to more power? Trade your 6 cylinder Trailvoy in for one with a V-8. You can't beat cubic inches, and nothing else sounds like a V-8.

We could always do without the extra weight though. With the right mods we'd have a better power to weight ratio along with better weight distribution.
