Yes, see if you can fimd those links. This has me interested. As I said above, I found the exact same measurement on the two distributors I measured yesterday and I'm interested in what the differences were as far as years and applications.

I think I'll dig out all the 289/302/5.0 distributors I have and check all of them. This may be another one of those mysterious inconsistancies, like the guy who say that he has a late '80s 5.0 with factory 28oz. imbalance...an impossibilty according to all my books, but there it is.
