Pertonix kit just gets rid of the points; the mechanical and vac advance stuff still needs to be set up right, as does the timing when you put it back in. Summit M-series 500 cfm carb, unless you happen to have a good 4100 1.12 lying around.
If having it look stock is most important to you, then the factory 4v manifold would be fine. Otherwise, I'd put on a Weiand Stealth, and (if money's not a problem) some AFR 165 heads.
When you ONLY drive around in-town, you can get away with steeper gears, and the 289 does not mind RPMs much with its short stroke. You could maybe even go with 3.73's if you never intended to get it out on the highway. They'd sure be fun! But if you occasionally get it up on the interstate, I'd keep to 3.25 or lower gears, just to ensure double-digit economy, and save wear on your u-joints, engine, and ears.
