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.
