    After lot of other projects I get back to my twin turbo 4.6 project
    I have here two sets of FR500 cams. One was used and mot possiple to degree right. When install all factory there are 35° out of direction !! But that are used ones and I not now where there used, but they have lift and duration of the Fr500.
    So I install the NOS factory sealed box FR500 that I bought when Ford get them out.
    They degreed right but the intake cam have only 208° @.050 !!!! Intake and exhaust habe exact same duration.
    The intake sould have 212° !!!!
    Is there some that have used the FR500 cams ?

    Thanks

    I've had a custom cam that was way out of wack. I just skipped a tooth to get it to where I could get it to a point to start degreeing them.
