IMO the problem with a new block is what do you put on top of it?
W7 8 9s are going to cost you some serious $$$$$. Other than the W9, which are running dry, you need to find some cores. GOOD LUCK!!
Now I'm not saying the W series won't make power, they do but sorry guys ancient tech!
Need the update the series with some new casting. P5 come to mind but that is old also and requires a different block which is another problem.
Hard core racers = Limited sales.
Stock LA = Limited sales.
