After GM went out of production with the Iron Duke, they licensed the design to Kansas Racing Products KRP Website They make new block castiogs that can be had with bores up to 4.125" and that will accecpt v8 heads directly (block is drlled for head bolt pattern) They also have cam blanks and crank blanks and different stroke cranks. These engines were used mostly in midget racing. real expensive but looks like it would be bulletproof. I would like to see one with a LS7 head the flows 400cfm, you would probably have to rev to 8500 rpm to make use of it.
