LS4 Swap into Bonneville? Has anyone every swapped an LS4 into any other FWD GM's? H Body? My mom has a super clean green 95' SSE Bonneville and it is gonna need a motor soon and would like to either swap in a northstar or preferably one of these new LS4 motors. Thanks, Brad

What all is involved in removing DOD? I dont want to have to deal with wiring the 2 wiring harness' together so I would want to keep the stock ecm and run the LS4 in standalone with a megasquirt and probally a cam and lifters (if possible). Will just any LS1 cam fit? Probally gonna be told to search because a couple of those ?s

Disable DOD? Just unplug the wires to the solenoids - the connector directly under the Intake's neck.
You may not be able to keep to original ECM. It depends on the year LS4 and on the ECM you have. 2005, and I think the 2006's used the E40 ECM, newer ones use the E67 ECM's. Those engines also used a different reluctor wheel, so you can't use a different ECM without swapping reluctor wheels.
