Got one for you guy's,

Yesterday morning mt truck started making a noise that sounds like a metalic buzz when I give it gas but stops when I let off the gas. Does anyone have any ideas as to what this could be IE;trans,rear end.
I've checked the drive shaft and it seems fine..
I have a '70 f100 w/ a warmed up 351C hooked t a C4 out of a '72 torino I would be vary grateful of ant help sense this noise is driving crazy
Thanks

 

Metallic Buzzz ?

Does the air cleaner snorkle have a little emissions valve on it?
They are known to buzzzzzzz !
