360 vs 440 79 coachman

I couldn’t tell you about the starter since I’ve only ever run mini starters on mine. As for the oil pan, you can run either timing chain cover with either oil pan, but if you are using an la oil pan, it needs to be a 360 pan (which you already have)
Ok, what are the pros to using a mini starter? Also any insight on whether the drive shaft length needs to be changed?
