I found this info on a website about a year ago. The problem is that I now don't remember which website it was! Times are for 0-60 sec

6 cylinder S/C manual 9 sec
6 cylinder S/C automatic 10 sec
6 cylinder N/A manual 10 sec
6 cylinder N/A automatic 11 sec
4 cylinder manual 11 sec
4 cylinder automatic 12 sec

All of these were give or take a tenth of a second or two.
