    Awhile back I posted that the drive had failed.
    Well I diagnosed the problem without taking it apart. /forums/images/graemlins/shame.gif
    The failure was the oil pump, it locked up.
    That was the horrid grinding noise, it sheared the shaft and steel coupler sleeve and wiped out the distributor.
    Grinding gear noise plus screwed up timing led me to believe that the drive had failed.
    As soon as I get around to it I am gonna take the pump apart to see why it locked up.
    On a side note with gear drives there has been some statements as to the harmonics wreaking havoc on the cam bearings.
    It appears that statement is true.
    The #1 cam bearing had started to delaminate, pock marks all over the surface, could be one reason the oil pressure started to drop.
    Or between that and the pump... who knows.
    At least it did it in the driveway.. /forums/images/graemlins/waytogo.gif
    It's a shame that's the end of the 73, that was one awesome rig.

    As an engine builder cam bearings rarely go bad, i will bet your pump took a crap and that wiped out your cam bearings. All it takes to lock up an oil pump is a VERY SMALL piece of silicone sealer or other debris.

    If I was single with no kids, lived with mom and dad and...
    I do have another 454 on the stand, another 350 4 bolt main and plenty of parts to do it.
    But..
    It's the whole time and money and a place to work on em thing.
    Right now I just want to concentrate on gettin the K5 going again.
    And that is takin up most of my spare cash.
    One day when the K5 is done, HA... I'll get into building another rig.
    And when I get around to building another 2 wheeler it won't be a 3/4 ton truck.
    As fun as it was I want to build something else.
    And a 2 wheel drive 3/4 ton rig is pretty much worthless IMOHO. For me anyway.

    I've gone the cheap rought and dropped in the $200.00 used motors more then a few times. But if you don't have the time or room too do it yourself, it does tend too become more then it's worth.

    It would be worth it but after 8 years of havin the rig I am pretty much just tired of it.
    And I spent $400 on a "good" engine that I am now rebuilding for the K5 LOL
    But I traded the plant from the 73 to Allan for a good set of SBC heads and a tail gate with good glass.
    The front clip is going on the K5 and the doors are on it now.
    The rear suspension is going to be incorporated as well.
    So it isn't a lost cause.
    I got alot of use out of it and had lots of fun, now it's time to motor on.
    In other words I got my moneys worth out of it.
    Besides that is like the 10th 2 wheeler I have had it aint like it is a classic.
    Now the 72 Camino in the feild I have been eying is.
