Ok cool, so will the ls1,2,3,6 intake manifold fit on a lq9 or the L33 5.3 engine? Since I have not made my final decision as to which motor I end up purchasing. Also if anyone can help me out as to go with a cable throttle body or the fly by wire? How difficult would it be if I did go with the fly by wire to do the swap? What are the advantages to using the wire over the cable throttle body?
