Go with a 3.55 gearset and youll get the best of both worlds unless you want to spend the cash to get a GEAR VENDORS under/overdrive tailstock for the transmission, you won't be sorry if you do
Change out the gears to a lower numerical number like 3.08 if you want but 3.73 is really not that low.
Installing a 4 speed auto like a 700r4 can also help at lot.
Plenty of people run 3.73's for street and strip, just needs the right tranny and OD for highway. If you run a 350 with a big cam and OD with 3.73 rear it can really lug an engine though. Check with any of the numerous A, X, or F body forums out there on a good tranny-rear diff. gearing combo.
