We report on the measurements of the W boson and top-quark masses
with the CDF II detector in p anti-p collisions at s**(1/2) = 1.96 TeV at the
Fermilab Tevatron.  We highlight the major features and uncertainties for
the W mass measurement.  The top-quark mass measurements are presented in
each tt-bar decay channels.  The combination of the most precise
measurements from CDF to date leads to M_top = 172.4 +/- 1.5(stat.) +/-
2.2(sys.) GeV/c2, corresponding to a relative uncertainty of 1.5%.
