You need to decide what you want. You ask about a cast crank in a 500ci stroker then mention an aluminum block???? And the T56 is a joke behind that as Tom Wells mentioned. If you look in my gallery you will see a 1050HP Ford wedge. The dyno pull was with a single Ruppert dominator we never made a pull with the injection. I don't think the numbers would have changed much. These motors make great horsepower with a mild combination. The problem is when you start turning RPM in these motors the block and crank often fall victim of the heavy rotating assy. If you want 800+ HP you need a good block,crank,light rods,light pistons,and quality valvetrain components. Just figure 20K+
