Strip the Centurion, build up the Miyata, and hammer away.
Sell the Centurion frame and use that $$$ to fund the eventual Dura Ace group for the Miyata. (just make sure the kid you sell it to promises not to chop off the derailer hanger in his fixie conversion)
If it is a 1981, though, be warned that that era of Dura Ace is a bit weird (especially the AX stuff).
Check the shifter bosses to ensure that they're compatible with the later 600 shifters from the Centurion.
