my 98 cobra is at 80xxx miles and at 100xxx i was wanting to start in on the motor.Should i stick with the stock 4v heads or get new, i was wanting to get the 5.0 stroker kit for it also but have heard through the grape vine that i should stay stock displacement. Then to go kenne bell or procharger? I have been rackin my brain for over a year and i thought i would ask for some opinions. Also i was thinkin of building a nos motor but im up for suggestions. And my wife is leaving for Qatar which is next to saudia arabia for 6 months so its me and the stang, well and the freezing weather too,........lol i just might start my project early so she has a surprise when she gets back.
