360 oil change

I know there have been various threads on this topic, but I need to specifically know if an oil change can be done on a 360 with the oil "vacuum" pump advertised on many websites. The websites specifically say that their pumps won't work if there are any obstructions or sharp turns between the dipstick and the oil tank (sump).

Does the 360 have a straight approach from dipstick to sump? Will I get all the oil out, or will some remain in the holding tank (it's a dry sump system) or other areas?

If I have to do an oil change the old fashioned way do I need to remove underbody panels to access the drain plugs? How many and where are the drain plugs?

Thanks for any feedback.
