    Default LT1 with LT4 blower wiring harness options

    Ok, I know this is LS forum, but its all in the family I bought a LT1 out of a 2016 Camaro, Im having a DOD/AFM cam kit put in from Texas Speed, I also have a 2016 Z06 Blower Im putting on. Transmission is going to be a TR6060 with all this going into a 1986 Grand National.

    Question, can I just get a PSI or Speartech LT1 harness and get one of this LT1 / LT4 Conversion Plug & Play Wiring Kits and call it a day? Anyone done something similar? Im running a Walbro 450 in the stock GN tank, as I have the LT4 pump on the block so as long as I feed the 60lbs to the motor/fuel pump I wll be good. Im only running 650-700rwhp ish.. I want to run a stock computer as its nice to have all the reverse lock out and OBD2 ports for monitors.

    They can do it no prob. The LT stuff is pretty close to being caught up with LS swap stuff at this point.

    You might want to look into the LT4 injectors too if you already have the LT4 pump.

    If you have the stock harness you could also do a harness rework and save a few bucks. These guys can set it up for a T56 if needed.
