I have wanted these cams for a while , i recently talked to Comp Cams and they said that Ford out sourced 3 different piston company's. So 3 different pistons are in the 96-04, So its a crap shoot knowing if these cams will work! ! .I have heard of people having P.T.V problems, and some not .Yet every time i call or contact A.M they say they will work on a stock motor, with retainers and upgraded springs. I have also researched some say install both cams on 109* intake center line and it will work and some said you degree the cam and it will work. Others say that this cam wont work without noticed pistons, A.M wont take them back if they don't work i'm out of the money for cams and install. ..Anyone have any ideas? i'm running a 01 gt with romeo block.
