So I pulled this eaton off my 03 swapped notch today. I was under the impression that it was stock. well after taking it off I discovered it was ported. Im not familiar with the companies stamp thats on it. Its stamped.... MMP 3. Anyone familiar with this. Its going to be for sale and Id like to know as much about the portwork as I can. You can see the stamp close to the very bottom of the picture.
