So what is it? It's really a very basic set up that has been dialed in over many years to run like more than it is. Started out with a 97 Explorer Long Block with 95k miles, back in '06, add a AFM-B-21 cam, trick flow valve springs, retainers, pushrods, professional products upper/lower, tb, underdrive pulleys, e-fan, bbk 1515 shorties, 3.73 gears, z-code t-5, koni adjustables all the way around, converted to mass air with an a9l which I tune with a Moates Quarterhorse. Best so far is a 12.47@108 or a 12.48@110 out at Lapeer at 2750 density altitude.
