Well playing devils advocate, it sure wouldn't catch any alluminum, and as far as I know that engine is mostly if not all alluminum. I do however have one on my 1970 Camaro that has a huge cast iron block. And on each oil change I seem to be able to pull some iron bits and pieces off of the magnet. Whether or not it would make much of a difference I don't really know because it would have been caught in the oil filter anyways. This may be an interesting thread.
