I'll be changing the pistons on my 360/426 stroker

THANKS GUYS I will weigh the pistons see if there is a difference between the new and old old bob weight was 1800 or so hope i don't have to rebalance . old days just swapped pistons , ogf course back then paid less for my car than the engine i built now , it will hurt if it grenades because i cheaped out .
All the new pistons are the same weight +/- 1 gram
