Planning on a 5.3LS s10 build as soon as I find the right swap truck. Which year 5.3 do I want,and what donor vehicle should I look for?Im a bit confused on where to start. Whats the differences as they get newer? Planning on a 224 or 228,ls6 intake,swap longtubes,either ported 5.3 heads or 243s,a stall,and maybe a shot of nitrous eventually. This wont be a DD,just a track toy/car show cruiser/fun car.
