I got a duel point dizzy for a 440
old mallory,it has 4 cam lobes on the shaft
one set works 4 cyls and the other set work the other 4 cyls
but they do have them with 8 lobes also
it gives a much hotter spark with duel points is the reason..from what i under stand
what kinda duel point do you have?
mine has a 2 piece cap that holds the wires to the cap inside on the electrode pins
had solid core wires on it also
also its a mech advance not a vac advance
would have a performance advance curve
its all greek to me but will be useing it soon,may throw a pertronix points conversion in it to ease the pain of setting both sets of points but keep the performance mech adv curve
