I have a 1977 440 police motor forged crank.
3000 miles on it. It has a bad vibration in it at 1500 and 3000 rpm. Runs good ran 13.7 In the quarter. Its in a 67 charger 4000 lbs I'm wondering if anyone else has had this problem and what it might be. The harmonic balancer is the right one and the converter is properly wieghted. |

77 440's did not come with a forged crank from the factory, police or not. If you added a forged crank to the 77 440 then you do not need a balance weight on the torque converter and you need a forged crank balancer. If your running the 77 harmonic balancer with a forged crank you did a bad thing. Did you balance the assembly when you rebuilt it?
