will a 100% complete ls3 drop into my truck? pretty much will the 4l60e and wire harness work n everything? the truck in my sig

 

Yes...BUT you'll need the knock sensor harness(moved from valley cover to side of block) and cam sensor ext harness (moved from top rear to front cover)

Besides that stuff a retune..Nothin major..

 

And a 24x to 58x reluctor conversion module

 

Oh yeah had a brain fart on that

Also Lingenfelter sells all 3 harness's

 

your 58x to 24x box has long enough wires to take care of that for you so no need for that harness. also why pay 55.00 for a harness when all you have to do is cut/solder/shrink wrap you factory knock sensor harness to reach the side of the blocks. 10 min worth of work to save 50.00 i think id take that challenge. also you have to drill the side of the block with a 11/32 and use a 10mm 1.5 tap to be able to thread in your old knock sensors. also you will have to delete the VVT if you plan to go with another cam. swap over your ACC from your truck too. you will also need a 4 bolt 90mm DBC throttle body bc your intake setup will not swap over.
