IMHO this is only practical when you've reached a point of development where more inches is better use of money than the existing available parts.
Makes boost look cheap, don't it?


How is boost cheap when it quickly can push well beyond what a stock block can handle?Anything in a Mopar block other than a Hemi that is over 700hp is pretty much on borrowed time. Strokers with good heads already hit 700hp easily....So adding boost is like burning the wick at both ends...These are the kinds of blocks you need for boost.
