    [QUOTE=cyclone] The rear of the camshaft also contains a gear which drives the distributor ......QUOTE]
    Well, no. The distributor gear is on the FRONT of real engines. Couldn't resist stirring the pot a little.........

    Cams don't close valves, valve springs close valves. Cams determine when the valve can close, but it don't close it
    Ok, I got my digs in! I'm out
    Actually, on Desmo engines the cam DOES close the valves.

    Id like to hear about the way to choose a cam. What things do pro's consider when coming up with a custom grind cam?

    That'd be a choice between 3/4 or full race.

    I think those two choices are at the bottom of the page.

    My contribution in a nushell.
    The cam controls the timing and velocity of the mixture in, and exhaust out, relative to piston position. Now where does scavenging fit into that sentence...

    A camshaft's purpose is to expose dissension on internet message boards.

    A cam normally breaks in half(or more peices) after a rod, crank, or other part gets in its path, ultimately making the inside of the block look nice.

    Fills the oil filter with metal particles when #6 exhaust flattens out.
