Comp cams xe268h for 318

In all likelihood your new pistons are not gonna be the same weight as the current ones, or even close; so a rebalance is gonna be mandatory. Grab a balancer off any 360 of like style, and you are good to go. You will need a special puller to remove or replace it. LAs are different from Magnums. Used are probably OK (mine has a qtr million miles on it.) One thing I would do tho is check the indexing BEFORE you send all away to be balanced.
