2. pullies

do not think this will have you up there with the z28 but you will be right there
, you need to work on your exhaust and suspension, the biggest thing I see on this site is how can I make it faster. I feel that you need to do your mods in stages and not just what makes it faster.
I would start on the exhaust , h/x pipe , headers ( short or long , long tube would be better) the a cat-back system I would get last for the exhaust. But a must to have.

But you must all so do the suspension , I would drop your stang from 1 1/2 in to 2 in , sport spring package , get the cast/camber plates and then put on some good struts and shocks, then sub-frames and then the upper and lower control arm. There is alot more to do to the suspension but this would be a great start .
You can add all the power you want , but if them tires just spin your a-- out ! But the exhaust is a great place to start because your year comes with the PI heads and we all know they are the best heads on the 4.6 to date. Have fun with all the mods , I have said this on the site before ,

One mod leads to another and to another and so on !!!!
