me dealing and building bottom ends i always advise everyone to get your bottom end balanced always its not necessary but it depends on what crank lq4? then yes balance all day ls2 crank? then yes but you wouldnt really have to...as you can tell i love to have everything balanced and on par i dont cut corners dunno if that helps you man

There's probably a big difference between the weight of the LQ4 dished pistons and the LS2 flat tops. At the very least, one should at least weigh the two to see what the difference is and see if it's needed or not. Not everyone would cut corners like you.

It's always a good idea to balance a performance motor. A 15 gram weight difference @ static conditions becomes many pounds of force at 6,000 RPM banging against your bearings in an unequal manner in unequal directions. Are many fine without being balanced? Sure, but you're better off doing it and knowing it's right vs hoping it's right IMO.
