1978 Ford Inline 6 & MSD 6A #6200 - forumsey Sep 28, 2007I have a 1978 Ford F-150 4x4 with an inline 6. It is a 4 300 cu. in. engine. I also have a MSD Blaster 2f waiting to be installed. Before I install I want to upgrade to a MSD ignition. I believe the right part would be the MSD 6A part number #6200. However, the 6200 is listed for 4, 6 (V-6 even fire only) and 8. I am assuming that it would work on my 4.9 which is a straight odd fire 6. Msd Ignition Digital 6 Plus Wiring Diagram | Diagram May 03, 2019Wiring Msd 6 Into 1978 Ford Data Diagram Update.
