Crazy knock trouble?

[chanley talon]

Alright all was well until my harmonic balancer broke. I replaced it and i still am getting crazy knock . If i blip the throtlle while driving it spikes to like 20 counts ? Just bliping while in gear causes bad knock. I just put in 550s and a aeromotive afpr . I didnt change the fuel filter though. I wonder if that is causing it? It was doing just fine and now its getting knock . Ill boost leak check it to . If you have any sugeestions id love to here them.

Alright the problem was the timing marks was off a couple teeth ! Also i had a piston ringland that was busted. So this was the answer to the problem this time.

Goodluck. Let us know how its going when the rebuild is complete. Maybe its time for a full buildup.
