SCAT Rods Weight Variation

Looking at the balance sheet i have for two sets used.....

Big end...431 g small end 170 g = 601
Big end...415 g small end 181 g = 596

Getting ready to balance another rotating assembly....will look at the box weighs...got a couple sets....already changing pistons as the JE are 20 grams lighter then the Wiseco stroker pistons.
