Starting to gather info on building an iron block 6.0L Gen III to replace my LT1 in a 94 TA. I am starting with a complete used 01 truck engine. What is the best bang for the buck mods? Which heads, cam,headers etc.. to use? It will be a NA motor, as cheap of a budget as possible. I was planning on keeping the short block all stock for now. What all has to be changed from truck to F-Body to make this work? What should I do for the wire harness and PCM? What about fuel lines and pump? Can I modify my current 94 A4 work with this setup? Pretty much the rest of the car has been updated to 98+ WS6 specs, now its time for the powerplant. Thanks for any help.
