Agree with all the above, 4.10s, 95 %.
The 5%? If your stuff was mine, I might try 3.73s (if available in a dana).
There is no way you need 4.56, unless you were maybe running eighth mile ONLY. (And imo, still a maybe).
I have 4.56 and 29.0 slicks in my bracket car and cross the 8th mile stripe at 6700 to 6800 rpm. I tried 1/4 with those gears and 32.0 tire and was running out of motor before the stripe. Rev limiter was set at 7500.
