I would be interested in any info on the Advance curve for the HEI. I plotted these figures when I installed the HEI and wish I had put in a Adjustable vacuum advance .

No Vacuum .. Vacuum Hooked up ....... Diff

Idle 12% .............. 12% ..... 0
1500 15% .............. 31% ...... 16
2000 22% .............. 38% ...... 16
2500 27% ............. 40% ..... 13
3000 30% ............. 41% ..... 11

any thought on these #
Thanks
