340 vs 360

The 340 has the "Cool" factor and came with better parts in stock form.

The 360 is 20 cubes bigger.

Rev limit will mostly be set by cam/valve train.

On a custom build...... I feel (and this is just my opinion) that it really again comes down to ... Do you want to be able to tell people you have a 360 or a 340.

Seriously.... Both are great foundations for builds. If it wasn't for the fact that my car has a 340, I would build a 360.
