I really don't agree with going all one brand for everything. You just need to know what power you want, and where you want to make it, and build from there. The most important part of the motor is the cam. Do research on a cam that fit your needs, and talk to people that sell cams about what you want, i.e FTI, Comp, Crane.... Then I suggest finding a set of heads that will work with the cam you choose, and then an intake to complement the heads you choose. Its hard to build the motor you have now, for a motor you may build later or vice versa. If you install parts that make your 302 run good, and you decide to build a stroker, those parts now may not be good. Think of the future or you will spend way to much money, I am a perfect example. There are a lot of people here that have great combos, you may or may not want to copy someone else that has good results from there combo. I think for now, a set of LT headers, x-pipe, a cat-back of your choice, pullies, 3.73 gears, would make your car run better now, and also work with your future mods, but that is my opinion, and like you have probably all ready read, you are going to get a 100 different poeple telling you to 100 different things. In the end you are the one who has to make the final decision, and live with the final product, so take our suggestions and do all the research you can before you start. I have rambled on to long, now good luck with your decision.
