I have a 65 Barracuda Formula S with a 273 4bbl. I just got the car and it's in good shape, but needs alot of work. Anyway, when I tried to turn the motor over by hand I could not do it. I then proceeded to take all the plugs out and get the starter to try for me. By removing the plugs the motor turned over but very slow. The battery I am using is actually more cranking amps then what that engine needs and it's a good battery not old or half dead. What would cause the motor to turn so slow when there is no compression since I pulled the plugs out? There was no unevenness to the motor so I don't think one of the mains are messed up. I have no idea how long this motor has been sitting, but could a starter just be weak?
