Cast versus Forged?

a stock 360 crank wil handle 300-360 hp in its sleep...i spun one for 2 yrs to 7500 rpm for two years with heavy trw pistons and stock rods...the stock rod broke....

the rotating assembly was so heavy it has a total of 10 slugs of mallory metal in it...tried using it again, and with light pistons and rods the machine shop said they could would have to take 900 grams out of the counterweights asked if I had another crank......LOL
