Obviously the engine and trans, torque converter, flywheel,, motor mounts depending on what style you use,, i didnt use the ls mounts i went with sbc clam shells,,,but also the ecm and maf sensor, and any accessories that you want,, power steering pump, alt, starter, ac comp,, wiring harness only if you are going to try to build your own,, I bought the harness with mine but the dipsticks sawed it half in to with a sawzall when removing it so it was useless,, $150 wasted,,.manifolds unless your going with headers,,,most everything else you will need to go aftermarket for parts.
