    Default Shift Point Opinions

    Been a boring day here at school and I have been thinking.. What would an optimum shift point be for me? now I know I would have a better idea of shift point/peak power if I threw it on a dyno, but that will not be happening anytime soon.

    Some info..
    303 c.i.
    Eddy Performer RPM 2 Intake
    AFR 185cc heads #142
    1.6 harland sharp roller rockers
    x-303 cam
    unsure of valve springs, which sucks.
    24# injectors
    T-5

    I think the cam's operating range is something like 2200-6200 RPM. I usually shift around 5,800-5,900. According to the factory tach that is. Is that pretty realistic to shift at?

    Let's admit it, Fox's are an addiction.

    You will have to experiment but my best guess would be 6,000.
