Could it possibly be the drive shaft, or old engine mounts that allow the engine to bang against the firewall? Thanks
I had a 72 3.0CS for 29 years. The engine mounts rot and need to be changed a lot. That could be it. Where in the floorboard area do you hear the noise. And is it constant or speed-dependent?

Please tell me about the "full 5 speed upgrade." I had my 4-speed for the life of the car but would like to know what you did. Is it a ZF transmission?
