Marlin,

Does the Pertronix ignition conversion perform better than the points/condenser? - Yes, it gives you more reliable spark at high RPM.

If you put spring clamps on the rear leafs, do you put a clamp at the end of each leaf? Do you put them before the axle, after the axle or both? - In front of the axle, it makes the springs act like traction bars. If they are worn, put in some new spring eye bushings while you're at it.

Is it better to put strong shocks on the front or worn out ones in order to allow more travel, and therefore more weight transfer? Do worn out shocks on the rear allow for more weight transfer or do they contribute to spring wrap and wheel-hop? - Soft in the front, stiff in the rear. You want the front to rise up for weight transfer, but you do not want the rear to squat. If the body is squatting down over the rear axle, it is unloading the rear wheels.

Hope that helps!
