Can't figure out where this chatter is coming from, please help

When you push the gas all the way to the floor there is a little chatter(not really at hight rpms, but just under a load) that I at first thought were the valves but now I am not so sure. It doesn't seem to do it when the car is in neutral, or when you are just crusing. But if you really give the car all of the gas pedal you can hear it. And I am not talking about taching that crap out of first and second. Anyone have any ideas?

Sounds like you are describing detonation which can be caused by several things. The first and most obvious are: What is your timing set at, and what octane gas are you running? Too much timing and too little octane will cause detonation.

Theres several other things it could be, but those 2 things are the place to start.
