340 Rods, speed pro L2316F “stock” weight is more than stock piston

I’ve done the same but mine were 30 grams off. Put it together runs very smooth. Balancing is always best. At the time couldn’t afford it. Motor has been shifted between 6500 and as high as 7200 for 10 yrs. just freshened it up. Probably could have reused the bearings. Mopar are tough.
