360 clatter - High volume oil pump/deep oil pan

don't forget to see that the port plug is in the lifter passage at the rear, right above the distributor drive gear. remove the dist. and look in the hole.put your finger or a mirror in thr hole and look for the plug. i forgot this pipe plug on a 360 once 20 years ago and it drove me nuts trying to get it to shut up.good luck,postcar.
