    cam ?

     



    I was reading some post that said a cam begins working ealier in a 400 compared to a 350 i know most manufactuer specs are based on 350's so if a cam were said to range from 1500-5800 rpm or 1600-6000 rpm were would it start and begin in a 400 sbc

    around 300 rpm's less depending on where you install it.

    More cubes (or a blower) tame a cam. A 283 will barely idle with a cam that works great in a 350. The bigger engine can lose more at bottom end and still run good, I guess. More to spare.

    Read what Pope says.
    A good torque cam in a 434 sbc will quickly turn into a "Pro street" cam in a 283.
