Loud rattle/grinding noise under my 97 Z28
Hey all, I've been having an issue with my 97 Z28 lately. When accelerating (and only accelerating, not in neutral) I get a loud rattle or grinding sound from underneath the car. It happens until 1500 RPM's then stops like clockwork. Every time. I checked my exhaust, no rattles and nothings loose, pulled off my heat shields, changed my motor and trans mounts, changed my oil, and it still happens. It sends a resonant vibration through the car and you can kind of feel it in the gear stick even. I'm at a loss on where to look next. Any info you guys could give me would be great. Thanks.

Clutch is fine, it's a brand new stage 2 (less than 1000 miles) and I had the same noise before replacing the clutch. I should also add that the noise doesnt happen under hard acceleration (over half throttle)
