Not sure but those were eagle forged rods that ended up going threw the block with only 30-40miles on them. But it sounded exactly like yours does until it did that.

I don't think so. But you might as well start piecing together parts to build a stronger one to handle boost or somethin.

weird question, but if you have an auto tranny, have you checked your converter bolts, or flex plate for cracking? it can also have a bottom end engine knocking sound as well. Also to me it doesnt sound like bearing failure to me, not quite loud enough and also rod knock does NOT get quieter when you rev the motor, it gets louder.

also if the crank pulley bolt isn't as tight as it should be it can cause a knocking sound

Not sure how i'd go about checking that other than tearing the motor out? Its certainly is an odd noise tho, when i hold it in gear and accelerateing lightly, but not soft, throughout the rpm range i can hear a strange clattering noise that comes and goes depending on the load.

You can take off the starter to look at the flex plate to torque converter bolts but to check the flex plate to crank bolts or cracked flex plate you either have to drop the tranny or pull the motor.

Edit:or you might be able to fit a flex camera in there to take a look i don't remember how much clearance there is with the starter removed.
