Some of this will depend on if you've maxed your fuel system already... if you have significant fuel pressure drop off as the rpms climb, then I think an SVT focus pump will benefit you. The last thing you want it to start detonating @ 5000+ rpm. That being said, I can't comment on the BBK pumps, but if for some reason you decide to go that route, be sure you get a pump for a returnless fuel system.
