I'm editing a Python file buffer in python-mode, and I want to quickly evaluate a region, so I select the region and press C-c C-r. Since I enabled cua-mode, that turns out to be a command that 1) copies the region, 2) backward searches.

I then found actually if I press fast enough, C-c C-r sends region for eval, if not, C-c C-r runs copy and backward search.

Is there a way to change the delay? It is to fast.

There is indeed; customize the variable cua-prefix-override-inhibit-delay, whose default as of Emacs 24.3 is 0.2 seconds. (You can customize just that variable via M-x customize-variable RET cua-prefix-override-inhibit-delay RET, or cua-mode settings in general via M-x customize-group RET cua RET.)
