What engine would you build for a Ramcharger?

If I had the two to choose from, no way does the 318 get picked over the 360. Cubes win out every time. I don't care about a roller schmoller whatever it is. That 360 would out pull that 318 comin and goin and never even have to think about detonation.
Especially in 4500 plus pounds of SUV!
