96-98 cobra cam options.

Scothew · 01-31-2005, 10:53 AM

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.

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.

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?

Scothew · 01-31-2005, 11:59 AM

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.

'93 Cobra?

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

Scothew · 01-31-2005, 01:59 PM

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.
