Still trying to decide on the route for my truck now that I'm keeping it. If I were to find a deal on a complete LS1, will it fit in the trucks? Mainly concerned about all the accessories fitting. Also, will my '01 PCM work or should I try to get the PCM with the LS1 if it's available. TIA.

 

The LS1 will fit in the trucks except the oil pan will need to be changed, as for the pcm a tune will take care of it.
