bigger is better and cost is the same now. i usually use 5.7 rods and stay around 6500. more torque in my opinion, i could be wrong though.

the longer the rod the better. you can't phsically fit a long enough rod in a 383 to hit the magic rod/stroke ratio number of 1.9 for a restricted engine, but getting closer is going to be better. i'd go with the 6" over the 5.7" every time. if you can get a 6.125" in there, do it. david vizards dyno tests in decembers speedway illustrated showed no gain in torque for the 5.7" rod compared to the 6" rod as low as 2500 rpm. the long rod outperformed the short rod througout the rpm range.
