360 vs 383

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
A 383HP? And if we are allowed slicks and headers maybe? I'd say mid to low 14s. Maybe 13.90s on a good day.
