Second carb: Oddly enough, most dual quad set ups for 302's actually lose power; especially at the low end. The only one I saw that actually made power was the Summit Racing kit. And it wasn't a huge amount of power, either.

Alum rocker arms: That will make the valve train lighter, but won't provide a significant power increase. If you increase the ratio, you can gain a small amount of power.

New Cam: Now this is where you can pick up a lot of power. What do you have now? You can use a pretty healthy cam without losing drivability and mileage, especially with 165 heads; which are perfect for a mild 302. Even with a moderatly large cam, your intake velocity will still be high. Go to the Comp Cams web site and read the descriptions and maybe pick a better cam.

Blower: Probably the best bang for the buck. You can easily pick up a 35-40% increase with 2-3 days work. But they can be tricky to tune. Lots of engine have been destroyed with a poor tune. So make sure you have a dyno shop that can tune this well. That will be expensive, but worth every penny.
