WARNING * MSD Pro Mag 12 LT PN 79081 and PN 79082 are designed to work in RAISED
CAM ENGINE BLOCKS using a DRY SUMP OILING SYSTEM only. They will work
in engine blocks with 50mm, 55mm and 60mm cam tunnels. Installation of PN 79081 or PN 79082 in any
other application is not recommended and can result in engine damage.
CAUTION If you have any questions or your engine does not fit this criteria please contact MSD Technical Support
at (915) 855-7123 for information and the correct part number for your application.
NOTICE 1. Install the set screw into the intake manifold or engine
block.
2. Install the magneto into the engine. On Chevrolet
engines, position it so the hold down clamp
will align with the housing’s anti-rotation collar.
3. Install the billet clamp over the set screw and on to the
collar of the magneto. Put the flat washer, lock washer
and the nut onto the stud and tighten the assembly.
Note: On Chevrolet applications, it is recommended to
locate the wiring harness of the generator towards
the left side injector stack (Figure 1). This also
puts the timing indicator of the magneto in a
position that should be easy to view. Also position
the band clamp’s retaining screw so it points to
the left and is in the back of the magneto, close
to the firewall. On Ford and Chrysler engines,
rotate the base until the pointer is easy to view.
4. Locate which cap terminal is going to be the
number one cylinder. Mark on the housing
this location then remove the cap (Figure 2).
