        as to the bumpstick itself, i'd suggest asking about a "negative =
overlap"=20
        cam.  the cam grinder you want to do biz with will know what =
this=20
        is and how to tailor it to your situation.  the minor added =
expense of=20
        getting a true custom cam will be more than offset by the =
results.=20
        IIRC, the latest tt porsche awd turbo used a neg overlap cam.=20

        Hi.  I'd like to know more about these "negative overlap cams".  =
Seriously!  What are they, and how do they differ from the norm?  Ditto =
on your comments about finding a cam grinder who will tailor YOUR cam to =
YOUR application.

        Walt.
