EL Prototype has cams for our 3.4 engine. My quetions are what kind of performance gians will I see. Do I need the SMT or another controller like it to run with the cams. At $150 per cam (4 altogether not a bad price.

 

OK dose anyone know what kind of performance gain I will see with a 260 Duration and 345 Lift cam. Can I use thi on a stock top end and bottom end.
