You gonna install yourself????
http://www.402motoring.com/product.php?car=Dodge Charger&itemnumber=N6sLh3KDtim6VSdXFetjWhat are the specs on the cam?
I bought the valve springs and install kit with it.There is very little lope with that cam if any,but it will retain MDS and get you 40hp to the wheels all by itself.Make sure you change the valvesprings when you install it.The stock 5.7 springs are too light at higher rpm.16 6.1 exhaust springs will solve that and they are very inexpensive to boot.
It's tame but better than stock. Shouldn't effect low rpm torque.
