Most important thing is to mount a fuel filter BEFORE the fuel pump. Holley pumps do not like even a spec of dirt. Get one that has a replaceable cartridge (not one of those inline ones) and mount it right before the pump and after the tank.

One thing I have to ask. You mention you are mounting it to the sway bar. Doesn't that bar move? You really want to mount it to a crossmember or frame member. As for the rest, it doesn't matter which side you run it down, just keep it away from exhaust and moving parts. Leave enough room so the rear end doesn't hit it as it bounces up and down.
