Need help with tuning my 340

Ok, here is the setup.
340 bored over .030 with 10.5 compression
mopar purple cam...484 lift
stock heads, not sure what version
tti headers
holley 650 cfm vaccum advance carb.
64 size jets in front, 68 in rear. I know small!
Havent been able to check timing yet.
Stock fuel system.

I have a wideband 02 sensor hooked up into my h pipe. The car runs really rich during normal driving. Usually in the 11's on the wideband.

When I first punch it it kinda stumbles but picks up quickly. Wideband readings stay pretty much in the 10's. Havent been able to run it at the track yet. Hopefully next week.

Any suggestions as to why it runs so rich?
