LT1 and speedometer weirdness

While in park, If i rev the LT1 up to 6000 rpm the speedo moves slightly also. It will reach somewhere between 5-10mph.

My stock '94 LT1 Caprice does that as well. I'd be willing to bet LT1 4th gens do it as well. I think it's just a glitch in the system. Odd, but harmless.
