Pistons for 97 suburban engine
 

From my understanding, pistons for a one piece rear main engine (like my L31 from a 97 suburban) are a little bit different and the cranks are balanced differently than an old small block. Can I use an generic chevy 350 piston without requiring a ton of work re-balancing the motor? I plan on bumping up the compression with a set of flat tops and I need to find pistons ASAP.
