Well, as you know msd provide degree bushing for the ignition timing advance.
The smallest one (physically bigger) one with less advance is 18°. Problem is, for the forced induction guys like me, need more initial timing like 18° and no more that a total timing of 30-32°
The degree bushing msd provide will not allow me to set my ignition timing the way i want it..
So, i did some reading and this is what i found.
The bushings are 0.1755" tall and have an inside diameter of 0.195".
They are camfered on the outside edges to help them slip into the slot.
a 14 degree bushing would need an outside diameter of 0.3865"
a 10 degree bushing need a O.D. of 0.3940"
So, now all i have to do is get the machine shop to make me some
.
Hope it help some other people.
