MSD is the leader in Ignitions, I tried to Adapt a Mallory digital 6AL #653 to a 95 Caprice with a LT1 engine and I could not even using the reccommended supplemental harness# 29008 too much splicing required, the Mallory digital box worked great on my 78 Caprice with HEI ignition. Had to switch over to MSD digital box #6201 and MSD coil #8226.
