    53 to 57 hood adjustment

    OK let me try and make this simple!!!!!!!!!!!!!

    I see hood hinges and pop-ups where the holes are extra elongated trying to fit the hood on 53 to 57 Corvettes all the time. That's because few know how to adjust or know what to do to make the hood fit and open CORRECTLY .
    1. The pop-ups are there to only lift the hood front line UP when you release the rear latch's pulling the hood cable so as to NOT chip the paint on the body.
    2. The hood HINGES are moveable (only a little to AID in pulling the hood FRONT area DOWN ) in the last few inch's of closing.
    3. The two fiberglass stoppers holes are elongated so that you can move them UP or Down to meet the thickness of the HOOD when closed.
    4.Now if the front hood line sits too high , adding shims ONLY at the hinge top bolt on both sides will canter the angle pulling the hood line down.
    5." Repro" pop-up AND rear male hood pins's springs {suck} because the wire is too thick making the front pop-ups to strong and cause the rear hood male pins to open when driving. ( if you cut a coil off to where the spring just put a little tension on the cup , your problem will be solved .
    6. Number 5 is why you see the hood male latch and female latch holes elongated also.
    7. A good looking working hood is when the hood front line pops-up at the same time the rear latch's pop-up, that's HOW it works PEROID .

    PS the reason you see some one using both hands to lift the hood if adjusted correct is because the hood bracing BOND has come loose from the hood skin.

    PS again the front hood hinges are designed to go OVER CENTER to pull the hood down compressing the pop-ups. That's WHY it has TWO arms!!!!!!

    Roy,

    Every time I close the hood in my '57, I need to push the front edge of the hood at both ends for the hood to close properly. That means the pop-ups need some help to compress. Is that the way supposed to work or by shutting the rear of the hood the front should shut properly as well without additional push? Thanks.

      If you have the need to push down on the front hood your hinges are not adjusted correct . ( or your using repro pop-ups/ the spring is to strong ) As I said the reason the hinges have TWO arms and not like the later 58 up Corvettes is that the second arm PULLS the hood down onto the pop-ups.(compressing them)
      If it's adjusted correct (hinge) then just as the hood closes that last 5 or 6 in. The second arm goes over center pulling the front hood line down. Now if the second arm needs more "over center" you add shims at the top bolt aiding the over center action. (not elongating the holes as most people do) 58 to 62 dint use pop-ups and was redesigned and the hinge had one arm!

      Do you understand now how it works.

        Roy,

        Great explanation...Now I undestand why the two arms in the hinge and what the second arm is used for (the top arm). Can you explain to me a little more the "over center" action? What do you mean that? Thanks.

          i had a problem adjusting my 57 hood. adjusted all the way down the front edge of the hood was about a quarter inch high when closed. the only way we could find to correct this was to pull the hood off, remove the radiator core support and grind off the square nuts that the hood hinges bolt to. i then lowered the nuts about 3/8" and tacked them back on like original. repainted the support and reinstalled. now the adjustment was in the middle where i needed it.

            There must be people with more brain cells then me BUT! When the second arm that is "fixed" in it's position moves past a certain point it pulls down (that is what I call over center ??????? Hope some one els can give a better answer here??
