Me and my buddy are taking the 350 out of his car and i was just wondering if we need to unbolt the flywheel from the torque converter? Does the flywheel come out with the engine?

The flex-plate (flywheel) stays on the engine. Unbolt the torque converter from it before you remove the engine.

Alright that saved me a lot of headaches.

Make sure when you put the engine back in that the converter is in all the way, turn it back and forth and push it in to make sure it is all the way into the front pump of the tranny. When the next engine is installed make sure that the flywheel dosen't touch the torque converter when you put the belhousing bolts in, then pull the torque converter forward up to the flywheel and install the 3 bolts.

alright thanks a lot.
