dual pickup distributor for a dodge 440 ?

the dual pick up electronic distributors came on the 76-79 lean burn (spark control command) engines. the lean burn brain controlled the timing advance/retard in place of the vacuum advance. the housings are the same for all V8 engines with the exception of these housings which have no provision for the vacuum advance, only the shaft was different lengths for different applications. i wouldnt even mess with the dual pick-up when there are superior choices for the EI
