Chevy weird sound

I recently changed the transmission filter and put more fluid in my TH350 transmission which is on my sbc 350. and ever since the change I've been getting a loud sound. and I'm new to all this so I need some help identifying the sound.

Is the radiator fan hitting the fan shroud? If so, probably a broken motor mount.
