2 barrel to 4 barrel

4.30 gears are way low for street driving. Drag racing, road racing with short straights and heavy towing, yes.
Depends if you really do any highway driving ? For intown I wouldn't mind 4.xx gears, right now I got 2.xx gears, I rarely shift into 3rd, I use my trans more like a 2 speed power glide with an OD. In second I can cruse 30-40 mph which is functioning like a 4-4.26.
