We are going back together with basically the same combo after our rod "mishap". Same pistons and crank, but a new set of rods (Callies Compstars we think). The new rods total weight are within a gram of our old ones. However, the small end is 10 grams lighter and the big end is 10 grams heavier. Seems with the piston/pin/small end total weight around 1170 grams (not counting rings/spiro locks), 10 grams differance isn't much in a 7000 RPM combo... What do ya'll think...
