SO can properly fuel larger injectors properly. SO is good up to 300HP, HO up to 200HP Max. Best bang for the buck is an SO pump.

If you have a s.o truck you have to run a s.o if you had a h.o truck you can run either. S.o is good for more hp. H.0 can only support up to like 500hp where the s.o is good for 700hp.

Only problem is if you order a SO pump most places will not accept a HO Core.
