''Pin cushions hold pins for sewing. They also sharpen the pins with the material that's in the center of it.'' -Quoted by my 7th grade sewing teacher.
If you had a broken wrist pin, the engine would have done blowed apart. Wrist pins don't brake in a Chevy engine unless it's a really modifyed engine. You probley are hearing a rod bearing knocking, You may have spun a rod bearing. You can start the engine and let it idle, Then being careful not to get shocked you can pull the plug wire off of the spark plugs 1 at a time, being sure to put it back on each time. When you pull the wire off of the cylinder that has the knocking noise in it, the noise may quite or get liter, If you find the cylinder when you remove the wire from the plug that makes the noise go away. Then that will be the 1 that the problem is in. If it's a rod bearing then the noise will almost go away, are even stop. If it does then you have a bad rod bearing. Time to overhaul the engine.
