Alternator relocation?

[Cheyenne350]

Hey all quick question, I'm about to get going on my LS swap 1978 c10 RWD and one thing I notice for my generation c10 is the location of the alternator they all seem to be above the pulley rather than bellow. Is this just preference or does the alternator hit the frame, sway bar. I have a LS1 off a 98 z28 to swap and the alternator located below, just curious to know so that way I could be ready with whatever kit needed rather than delay. Thank you guys in advance 👍🏻
