Contour Enthusiasts Group Archives Forums Modifications 3.0L Duratec Specs for 3.0 and svt heads

Ok, I'm having problems getting this to format correctly, so I'll explain it. This first pair of numbers is for the 3L and the second pair of #'s is for the 2.5L In each pair, the first number is the metric spec (most are mm) and the 2nd #, the one in ( ) is english, most are inches.
If anyone needs a better layout of the #'s, email me. (I threw a few other measurements in for fun )


Data is based on the 1999 SVT Contour 2.5L and the 2001 Taurus 3L

Thanks RARA

I have in front of me Ford specs for both the 2.5 (doesnt specify a difference between SVT or standard) and the 3.0L Camshafts and other various components. According to Fords specs there is no difference in these cams. Does anyone have proof that the SVT cams are any different? Troy???

hey can you post those specs....even if they aren't the svt ones i still need them. thanks

would we be able to figue out what kind of cam we need with a Desktop Dyno program? I have it
