Bent input shaft

What would a bent input shaft cause the transmission to sound like? Grindy and whiney?

bad/broken pilot bearing. Was the pilot bearing replaced on your last clutch install?

Yes, it was replaced, but could it just be that? It sure is loud and has a metallic grind and vibration.

bent input shaft? usually input shafts can twist, but that's usually with a good amount of power and some really sticky tires. and when does it make the noise?

EDIT: i just saw you're pulling 12.50, so it very well could be a twisted input shaft. i would go ahead and upgrade the whole transmission while you're at it, whether it's a rebuild, or a new tranny. do it right now, so you can throw more power at it in the future and not have to worry about it.

it makes noise when on the gas, goes away when decelerating.

any bad vibrations? does it go away when the clutch is pushed in? i feel like if it were drivetrain related you would hear it often.

No vibration, just when on the gas, nothing when clutch is in.
