uhm do not go with the ZEX kit i have that on my 5.0 and have had 1 accidental fire without my pushing the button..however on my 2v i run a NOS custom plate kit all stock without retarding my timing and run a 150 shot...i ran dry and wet..and if you use the plate that goes inbetween your throttle body and intake you feel it right away...def recommend wet shot and not zex
