A-Body New Guy

I just picked up a 1970 Duster restoration project and the first thing I did was sign up for A-Bodies only.com. I will be sure to post new question threads ofter as I'm sure I will have many.

One initial question I have is: When rebuilding my motor should I replace the stock intake with an after market? Or do I work to keep the motor as original as possible...same goes for the Carb?
