sounds to me like its hunting for idle at start-up due to a poor tune, my SS does the same thing. With a large cam like that on startup the car starts to hunt for idle and its related to the tuning.
You can search the forums for "hunting for idle" to find more info. What kind of tune do you have? should consider having it retuned either way.

the tach bounces while cranking and the surge sounds like if the gears from starter are slitely grinding .opti has 2000 miles on it.Im going to check the wiring to the coil and ignition module.
