engine balancing
So my motor is a mix of factory parts, ls2 rods and pistons, lq4 crank in an lq9 block. Does all this need to be re-balanced or should it be good since its all factory stuff?

Has this already been put together and run? Or is this a new build?
If it is a new build, its cheap insurance to have all the parts looked at by the machine shop and re-balanced as needed.

New build. Used parts obviously. Block was hot tanked, checked, honed, and assembled. Guy I bought it off of sold his car then sold the motor fresh from the machine shop.

If the rotating assembly is made up of used parts from different engines I would say you absolutely have to get it checked/modified.

Hum, ok. That's what I was worried about. The guy never mentioned having it balanced when I bought it. I'll have it checked out.

Definitely needs to be balanced. You didn't mention internal or external either but the mix up needs to be balanced together. A factory rotating assembly staying together is different.

I just assumed all ls were internal. So whatever a stock lq4 crank and ls2 rods require balance wise.

Getting dropped off next time I visit my parents in Jersey since the machine shop I want to use is only a town over from them. After talking to them on the phone it definitely needs to get balanced lol.
