[T3] Rocks in a tin can sound

[Gregory N. Cox]

I was driving my '73 Sqbk yesterday and in a turn lane waiting on a light. Engaged clutch, shifted into first and as the engine revved, a sound like rocks being shaken in a tin can started. I pulled off immediately and shut down the engine. After removing the hatch for a look, I then restated the engine. At low rpm, no sound. Upon an increase, the loud rattle states. 

Any idea where to start first?

Thanks!
