which way 200r4 or rear gear

[mikey531]

I am currently running a mild 350 w/turbo 350 with 4:10 gears. I need to do something for better gas mileage and highway driving. Part of me wants a cruiser with 3:08 and smooth running with decent acceleration not a racer. My old life as a drag racer wants to be able chirp the tires into second gear with part throttle, and well it happened the other day I left a stop and it started spinning and I didn't have brains enough to let off.. I figure being almost 60 no cop would believe it was me doing that anyway ! I am considering the 200r4 with the 4:10 and maybe having my cake and eating it too ? Or keeping the turbo 350 and changing the rear gear. Opinions? Suggestions?

Thanks
