Circle Track Digital Soft-Touch HEI Rev Limiter
MSD8727CT
RPM controller plugs into nearly any GM HEI distributor and functions as an RPM limiter, adjustable from 3,000-9,900. Unit additionally records highest RPM attained during race.
Flying Magnet Crank Trigger
The MSD Flying Magnet Crank Trigger
employs an aluminum wheel with four
magnets that pass by a stationary non-
magnetic pickup, causing the ignition to
produce accurate trigger signals. Pre-
vents false triggering from bolts or bumps
on the trigger wheel - only the magnets
will create the necessary trigger signal. Includes a 2-piece mounting bracket for the non-magnetic pickup that will work on either the passenger or driver side of the engine.

Super HEI Kit
MSD85001
Just what the Saturday
night racer ordered. The solu-
tion to the GM HEI’s loss of
power above 4,500 RPM, this
kit delivers more power, increased
RPM range, and improved throttle response. Includes a Digital 6AL ignition control, Blaster SS coil, coil wire and HEI dust cov- er. Ignition control includes the built-in Soft-Touch Rev Control to protect the engine from over-rev damage.
Soft-Touch Rev Control
To limit RPM, Soft-Touch computer
circuitry drops one cylinder at a time and

to prevent plug fouling. Smooth limiting
action holds RPM at the selected limit
plug-in modules for 6,000, 7,000 and 8,000 RPM (other module kits available). Adjustable for 4-, 6-, or 8-cylinder engines with points, stock electronic, or MSD capacitive-discharge ignitions.
