View Full Version : LS3 intake/heads on LQ4 Block

Hey Guys...doing my first LS motor Build and have a few questions. I have an LQ4 bock that I am planning to put an LS3 or Fast 102 intake on with the LS3 heads. As the GenIII motors have the knock sensors under the intake....will I have any issues with the valley cover (genIII)and knock sensors fitting under either the Fast 102 or LS3 intake?? Is there valley cover that would be better to use, or can I use the LQ4 valley cover?? What steam tubes?? Also, my understanding is that the injector plugs are different on gen III and gen IV????

Bringing a thread back from the dead via finding it in a search.

Im installing a Typhoon intake manifold onto a lq4 and need to know what steam tubes and valley cover/knock sensors i need to round up.
