Knocking 340

you have a sound clip ? Knocking from the bottom end that fade to a tick ? you sure about the pistons it has , that they are not some old forged pistons ? Best to strip it down see what you are getting

Im buying the engine thats already lying in the garage. So no way of getting a sound clip. I'll get it set up on a stand and investigate when i get it. In about 4 weeks time.
