Distributor springs ?

[Mikke H]

Does the six pack dist. hawe stiffer springs than a standard dist. ?

A slight difference, and perhaps the weights were more too. At any rate, the 6 bbl engines had slightly more advance than the 4bbl versions.
From the 1970 FSM:

Weights were the same for Prestolite dual points, cam stop slot and springs are the difference.
