I adjusted the valves when I put the valve springs on 4 weeks ago. The engine only makes the noise at hard throttle.

You may have an exh pipe close to a frame or crossmember. Check the mounts too.

I just changed the injectors and still have that strange noise. It is not the sound of two things rubbing, I just don't know. I think I might readjust my valves this weekend, maybe that will do it

Any luck finding your engine noise problem yet? Thinking also you may have air entering the system but then you would have hard starting as well.

When ... you .... have ..... the .... throttle .... peddle ....(foot peddle to the right) pressed ... to .... the .... floor. (WOT = wide open throttle) Is ...... what ..... you .... are ........ hearing ...... the....... injector ...... pump? (the pump that pushes fuel into the injectors, then into the cyliders based on the position and timing.)

Is that slow enough for you ???

Thats slow enough for me! I don't know if it is the pump or not because I can't get my head under the hood at the same time I'm driving that is my problem. I know it is coming from under the hood but thats all I can say. It will not do it in park, only when driving. It will do it at WOT + almost WOT and like I said it sounds just like spark-Knocking in a gasser ( thats the only way to explain it) It could be the pump-But what part of the pump would be making that sound I just don't want to break anything!!!!!!!HELP
