Hey so I have reset my timing to give me better idle but it may have to much advance all in. I was wondering how I could limit my total mechanical timing? All in at 40 degree's seems a bit high especially for Arizona, high compression, iron heads. Larger springs such that I don't get to 40?

Details:
- 1973 340 with stock iron heads, auto
- (unknown cam but very aggressive)
- Unknown compression >10:1
- New ignition system > MSD billet dizzy with an 6AL box coil
- Initial timing 20 degree's (idles much better here than at 15 degrees)
- All in by 2800 or so at 40 degree's (sounds fine with no load)
- Pump gas 93 max
