i would do minimal cosmetic work b4 engine work. You had your mind set in the direction of goin quick anyway. Everyone here, including urself, knows that if you make it into a sick lookin street truck before tuning the thing, you will inevitably pull up to a light one night and get your ass handed to you. That's no good.
IMO, stick with your plan of doing some tuning. However, a good cosmetic enhancement that will be functional is a cowl induction hood, to allow for a supercharger!
I couldn't get andy's auosport to load! ****it
