Need rearend advice - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just heard from the repair shop that the rearend on my 1970 Stepside has gone out. I thought this might be a good time to change gears. It has a 350 engine with some performance upgrades (Performer rpm manifold, Edelbrock #1407 carb, headers, dual 3" exhaust), and a Saginaw 3 speed transmission. I'm not sure what gears were in the truck. The mechanic thought they were 3:23 gears. He pulled the hub and counted the gears. Does anyone have an idea of what would be the best gears to run. I drive it mostly on weekends and short trips. Gas mileage is not a factor, performance is. I'm considering 3:73 gears. The tire size is 295/55/15. Any advice is welcome. Thanks.
