The advantages are perceived to be using a 318 block you already have. I think a lot of guys are intimidated at the prospect of sourcing and installing a 360. I also think that guys want to "do up" there current 'teen and are often disappointed in the outcome. This offers a very small stepping stone between 318 to 360. That is why I am trying to keep it inexpensive --So it makes some sense. J.Rob
