what cam would you suggest? i want it to sound nice and what would you suggest i do to get as much hp i can gain from this?

That all depends on if you want to spend the coin on a dyno tune. Usually around $500-$600

yeah im willing to i plan on taking my other car to get dyno tuned here soon so ill take my mustang ti

One thing to keep in mind. Dont get a cam for sound. Get a cam for the performance. If you go for sound alone you will leave power on the table throughout the rpm band.

yeah for sure i want gain more hp than sound obviously its just i would love for it to sound nice as well

So the next question is are you willing to change the springs?

 

[96blak54]

I think he can get by without changing the springs. Unless updating to new, but then again its overkill in my book.

Remember npi heads valve seat pressure is already 120lb where as pi gain a MUCH heavier intake valve, taller spring install height, which in turn created 90lb seat pressure.
