    Mark 8, termi, marauder, and the mach you should find all the same.

    All ex stock 4v exhaust cams should come out the same

    99 has more duration on the intake than the above.

    96 through 98 has a tad more than 99 and are the most desirable.

    "The same" were the exact words we initially were told about non-pi & pi cams. Both groups were different, but no differences in the group. That turned out to be false. Although,....i do agree there most likely wont be enough differences with the 4v cams.

    I think y’all need more cams. Obviously 2 and 4 cams just doesn’t keep y’all busy enough.

    And here I thought my life was complete only having to worry how one bump stick affects my life!!!! Lol

    The specs out for the 4v cams are based on actual measurements, not what ford claims. Many well respected people have come back and reported the same info.

    Spent some time mapping cams again. I must admit a great level of tranquility when doing this. Its so peaceful!

    Ive had the idea of swapping to 4v heads ever since the headgasket on my 5.4l 2v blew. I wanted to get actual 4valve open/close points on paper so that i could get the mathmatics figured out for a performance scenario. Lobe seperation and such....hold up. Let me explain.

    The 4valve heads have 2 camshafts that operate the intake and exhaust seperatly. One cam for intake valves, one cam for exhaust valves. The biggest gain here is being able to alter lobe seperation angle. This angle is referenced from an imaginary center line from the exhaust open/close points and intake open/close points and the distance between these lines.

    Its known that not much performance can be had by altering the intake valves operating points, but the exhaust is a different story.

    Yes, more intake duration has performance benefits IF....you want to purchase new cams....but in this scenario we are utilizing what we have available on the cheap cheap! Ford factory parts!

    Next post will be a big surprise! ...to the 4v community.
