Stroked 360magnun motor

Professional Products 80012 is a neutral balanced balancer. It comes with 3 different weights, one is for Magnum 5.9/ Magnum 360 crates. Edit : if stroking this, I would let the machinist make his thoughts, and confer them to you.A fresh stoker crank allows for a neutral balance , A question for you: What rotating assembly ? I still would have it balanced by a shop, if the supplier claims it's " balanced" ... A couple months back, a buddy balanced a Scat " balanced " rotating assembly. Pistons & rods were good, crank needed 30 plus grams removed, and less replaced in the crank counterweights to be within two grams across the board. Just a thought....
