I6 to 6.7L LQ4 with standalone fuel/spark?
I have an 02 LTZ I6 as my (now) DD and now just got an 03 LTZ 2WD with a I6 that has a rod through the block. My plan for this 03 is to swap in an engine I was using in my '73 C/K which is an LQ4 that's been stroked to 6.7L. (Drunk driver hit me and totaled it)
The engine also has MSD 6LS ignition/coils and a full MSD Atomic EFI with an MSD Airforce intake and MSD Throttle body. I spent a pretty penny on this engine so I'd really like to be able to use it. It only has 16k miles on it since built. I also have 2 walbro 255 fuel pumps and 1000cc injectors.
I also have a 4L80-E with a 3000 stall that was in the C/K that's controlled by an MSD transmission controller, I know this probably won't fit can I do anything I can do to make it fit? It only has 16k miles on it since it got built by Mad Dog transmissions. Perhaps I'll just sell it and buy a 4L60-E from them.
I've read on many other swap posts that I'll need new transmission mounts and a harness. My goal is to get rid of as much GM computer interference as I can. What else am I going to need? Will this engine even fit right?
I have a great driveshaft guy that can shorten the DS if needed along with a good fabrication dude.
So apart from engine mounts/AC Relocation/Trans mounts and wiring what else is needed? I would just go buy another C/K but I don't like how I fit in them so I'm on the hunt for a new project. My end goal is a sleeper Trail Blazer or my plan B will be a 1st gen 2 door Tahoe.
