its not a good street cam...I suggest a e-303 great for auto an 5 speed x303 is not good for auto unless you have a stall 2500 or higher

X-cam won't work with stock pistons.

depending on his pistons, it will , you will have to do a valve clearance check, or notch your pistons, easy to do, but that cam is just too much for a stock 5.0 get a E cam an be done with it, I ran a E cam an works fine

Not to mention you need to do a complete valve train set up with some 1.6 rockers,double valve springs, lifters, unless you got money , use the E cam you be happy, sounds, great ...an is a good street cam, but still can be nice for the track
