Keeping the bottom end stock? What are your goals for track results or horsepower?
For the cheapest good running engine i would mill heads and get them ported with larger valves, fast 92 or a ls6 intake, or get the bbk ssi if you dont have an ls6 and you get a good deal. and a proven cam.
I have a build thread with a 5.3l you can look at. I had ls1 intake valves in the heads and had a bbk intake with the tsp 233/239 cam. It ran really good but it spun a bearing before I could get to the track.
