If you stick with the 302, 2 1/2" duals is a bit large,
a cam for a 351W will fit, the engine will need to run the 351 firing order.
a 351 cam will act more radical in a 302, so a cam that is a little lumpy in a 351 will be noticeably lumpier in a 302.
Finned valve covers will not only add horsepower, but at least 20 MPH on the top end and double fuel mileage.
3.50 gears will make the car a LOT more fun, but will make the car busier at expressway speeds.
The above post should be read in a "Grumpy Old Man" voice.

^^^ oh that's right! Shocked yes those fins will allow the air to flow over those fins lengthwise, and should increase your top speed, especially if they are the old cal custom style fins!!! and make it more stable on the straight a ways WinkLOL

'rebuilder' pistons usually over compensate for the increased bore diameter with an excessing capacity dish to prevent the rebuilt engine from getting into an octane requirement problem
 
if you're going to re-cam the engine using the existing bottom end, make sure you don't choose a cam that asks for more static compression ratio than you have, overall performance will suffer due to reduced cylinder pressure. in general performance cams assume that you will have better than stock static CR, you'll want to choose a cam that improves cylinder pressure. indicators will be short advertised and .050" duration numbers and low or no overlap at all
 
the 'hotter' the cam the more static CR it wants

Any recommendations on ignition?  Will my existing Duraspark II be sufficient?  I found this post on HAMB, where a couple of folks actually recommended the Duraspark over HEI and others.
