Im tearing down a 99 ls1 motor and need to know the weight for stock rods, thanks

I needed to know the stock rod weight because I wanted forged rods and pistons and to balance a stock crankshaft without adding mallory metal. I double-checked rod weight on two different postal scales. Stock Connecting Rod including bolts and big-end bearing 22.6 ounces = 641 grams.
