If the sound occurs while the car is not moving (previously post) then it is not drive train. My hearing is not what it used to be, but it sounds just like intake air noise from Dellorto carbs used without the air box. I had to give up on my K&N filters and return to the air box configuration because my resonant intake noise was too loud during accelerations. Unfortunately, Dellorto air boxes are getting hard to find. If I heard correctly your noise follows accels. It definitely sounds like resonance noise. Since it appears you eliminated the exhaust I vote for the intake. Either way it does not sound like engine trouble. Engine sounds pretty good.
