3.8L needs crank, would it need rebalanced?

[cabech984]

I spun a rod bearing in my 3.8L GN engine a few months back. I am looking at getting a new crankshaft for the engine. I had the old rotating assembly balanced, would/should I get it rebalanced with a new crankshaft?

Thanks,
Chris

yes, not all cranks are created equal.

Not just yes but H E DOUBLE TOOTH PICK YES! There's a great deal of diff in the cranks and pistons. Be safe and do it right.

fair enough. I just dont wanna spend money where its not needed. If I pull pistons from the engine, would I be able to put them back in their respective cylinders without replacing rings? Its a relatively low mile engine that was balanced when it was built.

If Low miles & in Great shape then Yes you can but for $100 in rings I be real sure they are perfect before I put them back in.

Plus it wouldn't hurt to hone the cylinders to make sure they seat.
