360 vs 383

I've had three 360's over the years, none great but got the job done. None were fast, but I did not expect them to be. Pick up and two B-Bodies.
Just curious.... What would you expect a good running stock 383 in a '68 satellite @3600 lbs to run with 3.23's in the 1/4 mile? I just really want to know what your true expectations would be. Thanks
