I have an IBM 486dx2-66 but It does not list what voltage it is.
I could not find anything on CPU World website.
Anyone know ?

At first glance I'd say it's 5V. But according to this PDF it's 3.3V:

You can always start at 3.3V and if it doesn't boot or it's unstable, raise the voltage.
Requests are also possible... /msg kixs

Definitely 3.3V. It's also on page 18 of http://datasheets.chipdb.org/IBM/x86/486/40018.PDF (the V indicates 3.3V for a DX2-66)
