I'll try get one of the stock mag springs tested for spring rate and coil bind height. according to the info sheet for them sealed power replacements, the OEM mags calculate out a spring rate of ~240lb/in. It probably won't happen before new years, though.

anyhoo, here are some pictures. **WARNING, THEY'RE BIG** and darn, they show off every detail of how dirty these heads are from being yanked of a motor and sitting under a bench for a year....

The GM springs/retainers and the springs retainers on my mags (I'm assuming they're stock) are shown side by side. Magnum on the left, GM V-6 on the right for all pics.

hotroddave- do these pics parallel what you saw with these springs?
