That's the key. For more than you ever wanted to read about the subject, you can hunt down an oil thread from about 2007 on
www.correctcraftfan.com. The horse was pretty well beat to death.
There was a later thread over here, too. From that, it was somewhat settled that the MC engines that would need to be worried about these things are any Fords and the pre-vortec TBI Chevies.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.
