ONE of the biggest differences on the W116 engine was the ignition system..
Much higher output than the older 280SE/SEL 4.5 systems

that's what i was starting to think, that the W116 4.5's ignition was understressed in the stock configuration and thus could handle a bit of added resistance in the secondary.
tomguy,
during the 4.5s run in the W116, at some point they switched distributor caps from the "push in" type to the type with the male threaded studs. is this indicative of an entirely new/different ignition system than the ones on the W108/W109 and early W116 4.5s? (i can't remember off the top of my head if this switch occurred at the same time they switched from D-Jet to K-Jet...
thanks guys for taking the time to respond...much appreciated
