A couple years ago I bought an 89 Graduate, and the Alfa pro I had check it out before I bought it went on and on about how lucky I was that the number 3 cylinder wasn't "shot" yet. Something about how that particular manifold creates a horrible, imbalanced back pressure in #3, and I better install a free flowing header quick!!! This guy sure sounded like he knew what he was talking about. Unfortunately, he has had to close up his shop, so I cant pick his brain any longer. Anyone know what he was talking about?
