FC Coils on FD

FC Coils on FD
Well, my FD Leading coil is now dead...The car was bucking and hold back even if I tried to go full throttle.
I have decided to install a FC leading coil and a MSD 6A,
MY QUESTION IS, SHOULD I JUST INSTALL THE FC TRAILING COILS AS WELL and will the FD ignition run the FC Trailing coils without them being amplified.
Please advise, Thanks
Andre

I'm running the FC leading coil with the Jacobs Rotary pack ignition. My trailing coils are stock. Only the FC leading coil is amplified. I was assured by Chris at Rotary Performance that this setup would be good for about 550rwhp. So far about 2500 miles and no problems, idles smooth and pulls awsome. Gas milelage sucks but what do you expect with 850 primarys and 1680 secondarys. :-) I'm only running 10#s till tuning. I would check your trailing coils just incase. I had a bad trailing coil when I dropped the motor back in. But I would think that the MSD would work just as well. The reason for changing to the FC coil is because they have less of a chance of burning out when amping them.

I'm sorry wha?
Sorry I was thinkin about doing the same thing and I was wondering if it will just plug and play? Or do I have to cut into the leading coil wires and rewire them to the FC coil? And can I just mount the FC coil in place of the FD one?

I believe you have to cut the FD harness to wire it into the screw clamps on the FC, but I could be wrong. Also, the FD coil harness it only about $15 to replace.

Leading coil wires on FD
- yel/blue wire to the MSD's white wire
- blk/red wire to the MSD's (small) red wire
One important note on this install is that you must wire the orange and black wires from the MSD directly to the FC coil. You cannot use the stock ignition harness wires to make these connections since all three coils are interconnected to the blk/red wire. Said another way, do *not* connect the orange or black wires to any wires in the stock harness (especially the blk/red one).
