5.7 Hemi, 9.6 compression, caburated, mild cam.
Looking for a good starting place on a timing curve.
Where can I get the figures used for a LS9 Chevy shown on the MSD charts?

The blower is a Magna Charger model 122
The blower pulley is 3.4" so the drive ratio is 2.06 to 1.
The MSD system shows 8 lb. of boost.

Cam specs; Duration, I- 268 deg.
