Specs: what do I have and what do I need?

Hey guys, I have a 273 thats been rebuilt, all stock.
What lift and duration cam came stock in the 273?
what would a good performance upgrade be?
what carb/intake setup would go well for everyday street use, and give a little more power?

I am new to this again (its been 10 years since my last Mopar) and all the old Mopar info I had in my head has been pushed out and replaced.

help!
