Get the Crane electronic street/strip distributor.
Why:
1) Gear compatable with any cam.
2) AWESOME quality.
3) No weights or moving parts to wear out.
4) Dial 9 different mechanical advance curves with a twist of the wrist, dial 3 different vacuum curves.
5) Fits a Vic Jr intake with SLIGHT mods......a monkey could do. File down the water crossover bung at a 45 degree angle on the dist side, slightly file the plastic tabs that stick out of dist cap spacer.....done.
