[W126 Coupe] HEI

Why can't you adjust the timing on a 560?

What tune ups? 

What could you possibly do to tune a 560 up?  you can't adjust the
timing, there are no points, unless you have valve guide seals leaking
the plugs should last forever. 

Both 560 and 500 are Capacitive Discharge Ignition and toss a signal of
over 300 volts into the coil to initiate the spark. How HE do you want?

I have an MSD 6A and MSD coil, but the factory coil could have taken the
power, the voltage isn't much higher but the duration is much longer so
the totat current is a lot higher, and I use stock cap and rotor, so 3
of the 4 stock resistances are in place, I use "spiral core" wires to
replace the plug boot resistance and nonresistor plugs. Haven't had any
problem with overheating the distrubutor coil wire contact like I
expected. Been about 3 years like that.

 

PS don't ever get shocked by an MSD system.
