Allright im gonna try to describe this the best i can. i have a stock 84 H/O with the 307 of course, I get this weird noise kind of like a sound when something's stuck in a fan and kind of flaping back and fourth, Its always there when you start it cold, but then if you get on it when its warmed up it goes away. WTF??? It still does it in park so i can eliminate anything from the trans back. It gets louder as the engine rpm's rise, its not the smog pump as the barrings went bad so i cut the belt. The fan shroud is as clean as can be. So im lost as to what else could be spinning and making this noise? Anybody have any ideas or heard this???
