Distributor springs
I was thinking holes too. Seemed like a good way to be fairly consistant with the amount removed from each.
I didnt want to touch that distributor while still experimenting with the Chrysler made ones. It may not be perfect but its a decent working backup that can be popped in while experimenting on the others..
I don't know. They look different. lemme see if I have info on the Crane kit. Yea. Looks like they were in the package with a vacuum advance pod too. Crane 99601-1 I used that for another project, as were the springs.
Spring rate + the perch spread will determine the preload. That's what I call force of the primary spring(s) when its not spinning. That's a work around that will probably be needed. I also tweaked the spring lengths by bending the end loops. Not easy but doable.
My final setup was and is the Crane Blue and the MP Green Spring, both with the perches and loops tweaked. Without that, the green was much too long to be effective with only 18* advance in the distributor. 0.831" long inside the loops compared to purple which measured .795"
Here's some of the timing measurements plotted out. All of these were done on the car, mostly with an Innova digital dialback light. Take it for what it is, ballpark comparisons. I don't fully trust the dialback light at higher rpms or the MSD.
