Ive been looking around lately for a cam for a mildy modified motor. The Z-303 cam across and I was wondering what is everyone elses opinions on it. Pros, cons.. Would i have to notch my pistons with this cam. I hear a lot of good things about the x-303 cam so I would think it would be the same with the Z since the specs are really close between the two.

whats the specs on the Z?

 

duration- 290/290
lift- .552/.552
lobe seperation- 107 degrees
duration at 050 inch lift- 228/228

 

wow thats a BIG cam... with alot of overlap.... I doubt seriously that will clear the stock pistons without some work

 

yep i would just go with the e cam i think im going to go with a custom grind from comp

 

dominates my x303. How much are they?

 

It won't clear the stock pistons.

 

Isaac...What mods do you have in your mustang and how do you like you x-cam? If it clears stock pistons then that would be a better choice. I would probably then go with an x-cam and maybe 1.7 roller rockers.

 

I'm not sure if 1.7 with an xcam is a good idea with a stock 302. I love my x303 & it even went on without modifying the 302 to make it fit.
