I used the dirty dingo adjustable mounts and measured where my 350 was mounted and set the dingo mounts on the ls motor in the same location. Everything from there lined up the same as it was with the 350. If the intake manifold has a 3 bolt DBW throttle body you can bolt up the dbc TB . If the TB is a 4 bolt you will need an adapter. You also have to make sure if you go dbc that the pcm you use is compatible. The pcm has to have the drivers for the dbc setup.
