    H22 Type-S cams

    ok guys i just recently bought a set of type s cams off ebay for a really low amount, and ime having second thoughts on wether they are really type s cams or not, and i was wondering if anyone could link me to specs or tellme how to read the specs lol all i see most of the time is 275/267(not real type s numbers)? wtf does that mean? i know ones intake and the others exhuast but is that in .001" or what?, also where do i measure form to get the base diameter, from the groves in between the lobes or the cam journel?

    thanks

    do they have a blue tint to them? if not, they're definitely not type s cams.

    I believe the specs are on h-t in the prelude cam thread.

            well usually cams are read in lift and duration as well as overlap. they are measured in thousands of an inch by which you need a micrometer and make sure you are reading it right since some people mess up on that part

              yea im using a mic but they seem really low, and the cams arnt in the engine so that may have something to do with it, like the vtec lobe reads .390 but in the specs on that HT thread it says they should be
