I just want everyone here to know that Im going to be doing a full realm of tests and measurements on these "ebay" purchased manifolds and the AMS manifolds. I'm completely unbiased but I want the facts to be known about these manifolds and so forth. I own a flow bench so I can flow these as well.
And Don...im pretty good with measuring tools so no worries on having someone with not experience measure. What I find I will document and come back and post here. I just want this door to be closed so we can move on. I know many here have it made in their mind but for those who still speculate or want hard facts...I will be offering these soon.
