I have a 97 350 with the spider injection. Looking for a cam that I can put in for the most performance without doing anything but taking one out and putting the other in. I have a cai, longtube headers with no cats and a X pipe and most all other bolts ons. I heard the lt4 stock and the lt4 hotcam and the zz4 cam. Just want to change cam.

 

If you dont want to tune, leave the stocker in.

X2 and with any cam that is going to be worth it. it will need new valve springs . might get away with some 1.6 roller rockers but even those i would recomend new springs you could float valves at 5200 rpms without them
