I've just been thinking about, "What if..." these days. I have a used LS1 that I swapped out of my '98 Firebird for an LS6. I was thinking that if I didn't use it in my old car it would be a good swap in my 3T when the time came. One problem with that idea since I looked closer at the situation; pre-'05 engines used a 24X reluctor wheel on the crank and newer engines used a 58X reluctor wheel. The later system used a quicker ECM. The newer engines are generally DBW (drive-by-wire) vs. the older engines DBC (drive-by-cable). This is something I didn't think about 'til now. The LS6 engine I installed in my Firebird was DBW and I never really gave it a thought until now. That engine was one of the exceptions since it had a 24X reluctor wheel on the crank with an electronic throttle body. When I installed the engine I used the LS1 intake manifold w/ EGR and DBC throttle body and didn't have any issues other than the program of the ECM. So effectively, any engine swaps to be considered in my 3T must be forward compatible ('06 and newer).
