I have had my 66 I200 w/C4 since Feb 02. I have a problem. When the the car is first started there is a real loud knock.After a while the knock goes away & the car runs fine. It has been a while since I changed the oil. I have a new harmonic balancer to put on. The engine does rock a little bit. I had the front suspension replaced as well as the motor mounts. The shop that did it said the engine movement is not excessive, but he normally works on V-8s. It is a Mustang restoration shop. All suggesions or comments are welcome.
