Im not saying your wussy- im saying that you can get much more than 200 WHP from a 3L - around 240 is normalish for 2.5 SVT heads and cams on the 3L.
I MIGHT have a set of SVT cams to sell you soon- depending on how my own 3L build goes.
Also you might want to contact Kinetics racing- they build race Duratecs- they can grind you any cam you want.
