    Odd Vibration

    My 1964 falcon futura has a vibration at about 3000 rpm ish that is driving me nuts. I have a rebuild 200 which came with the car it has great oil pressure and compression , the c4 transmission was rebuilt by a local shop , I had a new drive line made for it , the differential was a ll redone , all the drive bearings are new the exhaust was done professionally I have all new wheels and tires. this vibration I have isolated to the engine or transmission which I had a new torque converter installed with the transmission rebuild and had installed a new harmonic balancer , water pump , fuel pump, alternator and fan blade. I made my buddy hold my exhaust pipe when i
    revved up the motor to the vibration and it doesn't seem to be a problem there.
    Any Ideas ? Any body good with this sort of thing ? I am more than willing to bring it to somebody if they think they have a good idea.

    I certainly don't claim to be "good with this sort of thing", however I did trace a persistent (speed related, not RPM related) vibration to a new Magnum 500 (Wheel Vintique) that was improperly welded and had 1/8" run-out. The wheel was replaced and cured the vibration. These kinda problems are difficult to pin down sometimes and can require a bit of luck to find. So.... Good Luck!

    Since your buddy was holding the exhaust pipe, should we assume it has the vibration when the car is not in motion?

    The vibration is not motion related. It is RPM related so I think it is in the engine or transmission. It does it in Park or neutral and also when driving but it is clearly there when not moving at all

    Gary (MacDee) had issues with vibrations on the Falcon before I bought it from him and IIRC it ended up being the torque converter.

    Maybe you got his old one somehow?

    Of course, Roger didn't tell you about the subsequent torque converter FAILURES!!
    If you do end up needing another torque converter, get it from Hughes Performance in AZ.

    odd vibration

    When the transmission was rebuilt they said they changed the torque converter. Still I think I will drive down and talk to them about it today.
    I went back to the guy I bought the car from last night. He went crazy over the car but said he did nothing to the engine . Darn I was hoping he was the one who put it in there or I could get a little history on it. Still it was fun to take it back and let him see it.
