    Can someone explain the power valve

    Here is an explination on how a power valve works. When an engine is idling the diaphragm ‘sees’ a high manifold vacuum. The diaphragm responds by moving in the direction of the vacuum, which overcomes the force exerted by the spring and pulls the needle into the seat, thus closing the valve...

    Classic Value?

    You can’t drive it till the radiator hose is replaced. Looks like it’s been gone for a while. I also noticed the floor on the drivers side is WET. That’s not good. More than likely the cowl is rusted out and that will take big bucks and lots of time to correct. The rust around the back...

    Rear Brakes Locking

    Sounds like the proportioning valve to me. If you still have the original, it might be a good idea to change it out. $89.99 is not that much if it corrects the problem. Just my 2 cents

    Lower 69 Mach

    What kind of headers if any are you planing on running? My Hooker Super Comps hang down VERY low at stock ride height. Just something to think about.
