Well I guess I'll chalk this up to a lesson learned. Here's my friday night schooling.
#1. Ebay SFI flex-plates ARE too good to be true.
#2 Apparently the previous owner of this engine had already advanced a tooth on the pump.
#3 You can hear what sounds to be a cracked flex-plate when the timing is too far advanced. Retarded my timing and the truck runs better, smokes less, and NO MORE KNOCK!!!!
