Distributer advance springs for a 318

Here is my car 72 Satellite Sebring
318 with a 904 Automatic
Dual exhaust with flow through mufflers
LD4B 4 bbl intake with a 625 carter on top.
A very very mild cam MP . 240/248 405/.410
Rear is an 8 3/4 with 3.23 open
MP electronic ignition with an orange box.

What would be a good set of dist. advance springs for this car ?? Car is used as a Driver

Thanks in advance
Fred..

If the distributor is a Mopar Performance distributor it already has a very light set of springs in it. That distributor will also be set up with 24 degrees of advance in it and for your engine that and 10-12 degrees of initial timing you are as good as you are going to get without getting the engine/car on a dyno where you can fine tune it.
