stock cam/stock intake/stock heads... i would say between 6K and 6200 will peak, if that high

i would agree with that statement... My personal best run at the track i just kept uping the shift points, it kept getting faster and faster... The fastest run was with the 1-2 6800 and 2-3 7000.... Last time on the dyno, mine HP curve kept pulling past 6600...

these number are from various dyno runs over the life of my truck, all with the stock intake...

PRC heads + 214/220 108+2 power to 6600+
Stock heads + 222/224 112+2 power to 6200
Stock heads + 220/220 114+4 power to 5800
