Since Nathan has mentioned you can remove the valve covers on a 96-98 car with the motor in the car, I am wondering if changing cams would be possible as well without removing the motor.

In the event it is, if a set of Mach1 cams were found for a cheap price, would these be a viable upgrade to help boost the mid-low range power of our 96-98 air movers. How would it effect the IMRC's or more like how would the IMRC's effect the cam profile.

Well, the valve job aside, PHP has been experimenting with stock cam swaps. Paul told me yesterday that they are finding 30 RWHP with the stock 1998 Cobra cams run on Mach1 heads. This is with no tuning either, just a straight-up swap. They also have seen results from 2001 Cobra cams. No pulling heads, just swapping cams.

FRPP Cams

99/01 Cobra's use the same Intake and Exhaust Cams
98+ Navigators use the same Intake and Exhause Cams
03 4V's (Cobra, Mach1, Marauder, Aviator) use the Navigator Intake Cam and 99/01 Cobra Exhaust Cam

I'm not sure about the cam specs for the 96-98 Cobra's because I don't have a pair to measure and no one will loan me a set. But I am willing to bet with the B-heads that you will not gain much by going with the 03 4V setup because of the swirlport/intake design.

This, of course, is pure speculation which nobody has been able to answer for me at all. I would check your cam timing if you pull the covers because our motors can be off up to 10* from the factory!

My vote is for something like a Crower cam.

. . . and no one will loan me a set.
Use your own damn set, you lazy bastard. :tlash:

:think: So you get more power from the older cams? That seems about dumb as hell. Why would Ford take a step back on the cams?

I read further and someone said it was due to the 96-98 having more lift and duration.. i dont understand cam profiles all that well so thats why I am asking it here.

it had a better power curve and i wouldn't have gained 30 rwhp by putting in an E7 cam

So apperently the mach 1 guys loose a lil bit of low end if they use 96-98 cams, but gain a ton up top.. would we gain any low/mid range and loose just a tad up top? if the curve is good, i would not be opposed to that.
