Hello my name is Michael Hill from Phx Arizona. I have an 86 C10 two wheel drive that I will be swapping in a ls3 engine soon in the winter time since its way too hot right now in AZ!!!! I have a RPM 4L70E tranny being built with a 3k Vigilante torque converter and a stand alone harness. So I will have tons of questions along the way hopefully I can get this thing installed and running by Christmas. Thanks Michael.
