RE: How is a 428CJ balanced from the factory?

Rich, the balance formula for most automotive and ford engines goes like this. You take the piston and pin weights, along with the rings and small end of the connecting rod weight, thats is everything from middle of the rod to the piston as one total weight, say 1100 grams. Now you take the big end of the rod_weight , and bearing and some oil weight and say it comes out to 700 grams, then you double that weight to 1400 grams. Then you add the two weights together to get whats called ( bob weight factor) in this case 2500 grams. Then you simulate that weight on a rod journals and spin the crank on balancer to see if your over or under balance. The weight is adjusted by drilling out weight on the counter weights or adding weight. Most cranks should balance out to 50/50 staying within 2 to 3 grams of your total weight, zero is best. One of the most important most over looked items in a rebuild is the balancing! when piston or a rod is 8 or 9 grams out balance it's like a 250 pound sledge hammer beating on your motor at 6000 RPM . Most people will blame it on oil the or the lack of it for there engine destroying its self, not even concedering the balance being the problem. keep your balancer and your flywheel neutrol except 428 flywheel.
