Does anyone use the Z cam and like it? My combo is a 93 cobra with a 331 JE 10.5 pistons and edelbrock victor jr heads trying to decide between the X or the slightly bigger Z cam. One other question why does everyone bash the 93 EECV is it really that bad, what's wrong with it? THANKS GUYS

Yes, the Cobra computer is horrible. It stays in closed loop for 7 seconds of WOT application, it pulls the most timing of any computer between shifts, it has very weak air/fuel curves, and it's timing altogether is weak. The Cobra computer is the WORST computer you can get for a 5.0, probably any car ever.
