Forged a lot heavier then cast and H beams a lot heavier then I beams. I running Scat cast crank and Scat I beams lighter faster revs less weight less stress on mains ect ect. My new at the time Scat cast crank was turned 10/10 to improve run out, taper, out of round ect. Had local high end speed shop balance crank rods and inspect rotating assembly. Then I bought tools checked clearances, run out, end play etc myself during assembly. During assembly I ran oil pump with a drill with crank in block but no pistons/rods and got a bunch of metal shavings in oil pan which would have been stuck in rod journals otherwise.....
