Well I don't fit in a Viper but they are sure nice to look at lol. Round ports are the Ram Air IV, 455 HO, etc.. Pontiacs. Figured you'd be an ace on these cars soon and you'd swap the Viper (jk).
Many of the new timing lights (like the one you bought) also have RPM function so it makes the job real easy.
Not sure what the specs on your engine would be but 36 degrees total (initial & mechanical) isn't set in stone so just measure what you have (you can set the light to 36 but adjust it to set the mark at zero) and see what you have after you bring up the rpm's. My 350 HO likes 33 total all in by 2500 for example. The adjustability is going to be the initial setting (w/o vacuum advance) and the rate (springs) at which full advance happens. So if the distributor is capable of a 20 degree centrifugal advance at 2800 rpm you would need 16 degrees initial advance if you were shooting for a total of 36. I think you have a good grasp on the concept.
