Seriously looking for help here, I've had this SOHC ka-t done for what seems like forever (5 years), but have yet to tune and drive it on the street due to other factors (mainly two kids). Anyway I am determined to get it running and finished this year since its about time I get it done.

I'm looking for some help identifying a noise, to me it sounds like rod knock, but it doesn't have the rhythmic increase the defines rod bearings. Could it be a crank bearing? Just looking for help, don't want to roll into the tuner with some bad bearings. Also please note, this un-tuned other then adjustment for larger injectors and MAF.

I'm prepared to pull the motor and replace the bearings/other parts, I just want to drive this car.
