I will tell you like I tell anyone who asks this question, spend time reading and researching the great vendors we have here on Lat-G as well as Pro-Touring.com. Look at all their products and decide what works best for what you want to achieve with your car. I spent the better part of a year just reading and researching parts before I purchased anything. The more you know the better the project will turn out.
Personally, I would concentrate on the suspension, brakes and wheel/tires. With the popularity of LS swaps there are some really good deals on early SBC/BBC engines left behind. I would back the engine with a good over drive transmission either auto or manual depending on your preference.
Take a look at the Ridetech 48 Hour Camaro. It will give you a good idea of what is possible with all bolt on suspension parts.
