wow that sounds horrible. can you pinpoint the noise location (front, back, top, bottom...) sounds like air passing over a reed, you can hear it whistle just after it dies like you have a intake leak. did it run this rough before you did your 5spd swap, will it idle on its own, does it make that noise when your foot is on the clutch, did you replace the pilot bearing when you did your swap?

Just off the top of my head I would say you are only running on 2 (maybe 3 cyl.

It allmost sounds like an extreamly bad alternator bearing but that doen't match with the swap.

I would say you hav ea problem with the clutch and or throwout bearing being installed wrong.

Drop the trans and check that stuff out.
