| | Controller kits GM vs Speartech
I am starting a Gen 5 LT4 install in a 1965 GTO. As far as the gm controller kit 19331517 vs Speartech's kit, which one do you like and why. Also I am using a T400 in the car and would like your opinion on a signal converter to the ECM I would like to keep the cable driven speedo in the car. Thank you in advance.
