G'day everybody,
I recently replaced my dizzy with an MSD 8456 direct replacment dizzy because the cam destroyed the balance weights on the old factory one and since then my NC 93 Fairlane Ghia seem to lose spark every now and then when at operating temp but runs ok when cold, I can watch the tacho drop to 1g and bounce straight back again when cruising along at 2g she seems to do it worse under load, almost like she has a stutter.  Straight away I thought it was the factory coil packing it in  so i replaced it with an MSD 5527 direct replacement coil but she still stuttered when warm  so I replaced the spark plugs and the leads but that didnt fix it either  Any ideas guys cause im all out

It's probably because MSD stuff is now total junk and regularily fails straight out of the box or within a short time frame. Its now made in China and quality suffered because of it.
They used to be good. |

Besides MSD being junk. There are no balance weights inside a TFI type dizzy. The EEC controls the spark advance, not the distributor.

Turns out they use a different TFI module in Australia compared to America, all i did was put my old bosch module from the factory dizzy onto the new Msd dizzy and she runs allot better now,

Actually, they don't use a different TFI module between Oz and the U.S. because the engines are fully imported but, if you mean that MSD use a different one yes, they use a particularly crap version of their own. In fact I don't think I've ever come across one that hasn't failed. If you still have trouble it's likely the Hall effect is giving you trouble because, surprise surprise...the MSD ones are s**t aswell

Great, thanks for the heads up, can i swap the old Bosch hall effect into the msd? And should i expect trouble from the msd coil aswell?

It should be a motorcraft hall effect but I don't know if the MSD is the same physically so it may not.
Just put the whole Ford dizzy back in. Just leave the coil there if it isn't playing up. |

The old dizzy didn't agree with the new cam, destroyed the internals under the hall effect

There are no internals under the hall effect other than the shaft and collar. How can a camshaft do anything to them anyway?
