After looking at the SHP I would say 700 would be the max on that block, The Little-M Sportsman block is rated at 900 horse according to Dart.
The SHP has less nickel content and does not have the heavy bulk heads on the front and rear and they have 3/8 outter splayed bolts and a little less cylinder wall as well.
It will take the GM spider for HYD roller cam set ups
