It's ALIVE!! My LLY powered 2003 "X LB7" truck is on the road!:D

It's only got about 10 miles on it so far, but all went well. We did have a little trouble with the anti theft. Getting the ECM, TCM, and BCM to all get along was a 30 minute relearn procedure and so far all is GOOD!!

We'll put the finishing touches on tomorrow and I'll try to log another 50 miles or so this weekend. Hopefully there will be no codes, and NO more LB7 injector issues!

We used a complete LLY engine, the harness from the LLY truck from the under hood fuse panel out, the LLY NSBU switch, one CAC tubes off the LLY and one off an LBZ, the 03 TCM, tranny, and CAC.

All in all not a bad swap!;) This SHOULD also open the door to putting a complete LBZ long block in too!! Thanks to all that helped!

:thumb: Congratulations, Rick! Hmmm, what if it turns out you created the only LLY in the world that won't... never mind!

And congratulations on finding the reluctor / crank pin issue on the '04! It sounds like it's only a matter of time before 'Ol Red is happilly clattering!

Thanks John! JK was out, and called back later (Thanks), but I got the info from the dealer. The main issue was bad batteries, then the anti theft.

Clean the mating surfaces of the tubes and couplers with lacquer thinner or Acetone prior to assembly. Any oil and they will pop off at he most inconvenient time. Make sure the ridges engage each other.

Everything is lb7 except motor, wire harness, and turbo tubes.

I'm sorry to have to say this, but I can fix the well known LLY problem a whole lot easier and cheaper than a new set of injectors for the LB7.

The LLY is cheaper to buy than the LBZ and it makes all 4 of my trucks very, very close to the same. Only need to have one spare turbo, one spare ECM, one spare CP3, one spare motor, etc.;)

Thats just being an efficient company. Saves money on parts. Good call.

A TX Christopher fix is all you need if it overheats, right??
