My first thought was that perhaps you have less power than you usually do,
causing you to hang at the rotation speed a little longer than usual. Did
you rotate by the same point as you normally do? Other things: Mag check
normal? Normal RPM on takeoff run?

Yep, everything checked out during preflight and run-up. The JPI EDM-700
engine analyzer showed 6 good bars (meaning all six cylinders were firing
normally) manifold pressure was 26-27, and RPM was nailed right at 2650 or
so at full throttle.
