Hoping someone can help!
I have 74 911 2.7 engine with a crane fireball xr700 ignition with matching coil. The tach is from a 76 911s This was done by the previous owner, My tach is 1000-1500 rpm higher than it should be. Does this sound like I need a tach adapter? what is comparable with a Crane fireball xr700. Are the MSD ones interchangeable? with crane devices? |
