I ordered an XE268, which will take a little low end away right now with my current setup, but should work even better with the 3.23 gears and if I eventually get a higher stall converter.

It is not important to me to have a lope, bc a lopey idle does not necessarily mean big power, but does the XE268 carry a lopey rough idle with the stock compression and drivetrain setup? I have heard this from other people, but am curious. Also, should I advance it 2 degrees for a little more low end? I did purchase some hooker competition headers as well for the setup.
