Those AJE/BAE blocks don't work so well for the Wedge head crowd, or the street strip guys. There is a billet water wedge block that is in the works but I am sure cost will scare most away if and when it comes. BTW just FYI a billet Dart water block for a BBC is over $14000 and they sell plenty of them
I have a Shelby FE Alloy block sitting here for the 63 T-bolt Clone, it was $7500+ shipping, Irony the closet HP to the Hellcrate is the 536Ci 750HP crate engine.....it's only $37,299.99
