I thought we had diff intake cams for torque? Like out of a 5.4 navigator or something.

heard the same but never checked on Navigator cam specs. Can't remember what the exact specs are, but I've seen the Mach/Cobra specs and they are the same.

That's true, and so does the Cobra. What makes them "different" is that they are different from any prior year 4.6L DOHC intake cams, and they did indeed come from the 5.4L in the Lincoln Navigator.

I heard that the '03/04 Mach 1s have the same motor as the termi, just not supercharged? Is this true? How much power will they handle?

Thanks for any info..

I had heard the same thing so this just completely blew my mind... I will say though between the two definitely go for a Mach1 they just look so much better and perform much much better. Down side is that the tranny is a piece of crap though
