Car Information:
Year: 1986
Engine Size: 5L
Trans: Automatic

Issue / Question:
The engine has a loud knock on right side at rapid acceleration only. It has no knock at regular rpm.

I would have to hear the knock, but I would suspect either a spun rod bearing or a large piece of carbon on top of a piston.
