Unusual amounts of knock at unusually low timing

[Danspeed1]

so far all you know is "there is a noise" and "your knock sensor filter doesn't discard the noise (probably because its loud)"

i really dont see where the ignition timing theory comes from

I'm with you Steveo, but what concerns me is the fact that the noise only occurs at WOT and sounds exactly like knock lol. I am not totally even sure how to diagnose it to be honest. I could try getting the car up on a lift and do a quick pull but the noise could disappear or change without the weight of the car. It sounds like its coming from the engine, but its a fresh rebuild done by a professional shop. And its not like anything else I've heard. Ill keep messing with it and post my results. On the bright side, plugs look great, not indicative of knock at all. So close to getting this thing done; one step forward to steps back.
