[the1andonlyGR81]

who has the 98 mark viii cam specs? i saw the 03 cobra's was 186/194 @ .050 with .392/.390. it just seems awfully tame, but i can have the cams, vs. spending 1300 from comp, or crower, but they're totally different and with xe 262 226/222 @ .050 with.425/.425 power 1200-5900 with redline at 6400 and with no computer mods until next step up your looking almost 450hp n/a streetable. i just have been trying with no success for stock specs for baseline. anyone? anyone? bueller?bueller?

When I did my brothers SS, I called Comp Cams and asked what the biggest streetable cam they had was. Then I ordered the next one in line that they didn't consider good for the street.

 

[the1andonlyGR81]

the thing is i can get new 03 cobra cams for 300. im not in a position to spend 1400 for cams although sean hyland has good ones for 795 but has a 300 core. the mark cams and the 98cobra cams have the same exh grind just more duration on intake. i just couldnt find the stock specs anywhere, just heresay.in 1999 when the cobra went from305 to 320hp the same cams are used in their current crate motors which are basically the 03 motors, one at 8.5cr for sc,and one at 10.5 for n/a. those cams are to which im referring. i mean if i have the heads out, again, it should be worth it to use those cams.the info i got
part #yf3z6250da (aa) is the left and r side exh. 186/194 deg@.050 lift.392
part #yl7z6250ba (AA) l and r intake the same numbers
according to right on the marks research (comp cams#ihave along with dyno results)
we're off a little bit but close ans it would seem the same cam is in mach1 and, navigator and marauder. that ill check. for 30 hp more, is it worth it. i think so. replies?
heres a link to the cam i was considering, found a site where its 400 cheaper its in a mach1 but sound should be same
http://youtu.be/3iw7IkSB_K0

 

[philly0420]

03 cams are the same as the mark from what I have read. The 96-98 cobras are the more agressive ones. If it were me I would go aftermarket and do the supporting mods with it if your gonna have the motor apart. Just my 0.02

The cobra cams are not the same as the mark8's.

I used 96-98 cams in my 04 cobra. The horsepower and tq curve was raised but about 500 rpms compared to the 03/04 cobra cams. I also degreed the cams, intakes were at 110lc and exhaust was at 114lc.

idk about the specs on 99. i do know that the 96-98 had 305 hp, 99-02 had 320. the terminator that came out was supercharged and came with specs shown, which are the ones used in their current crate motors (4.6l dohc) which are rated at 320, in 03 they basically bolted the supercharger on and voila. they are NOT the ones used in the marks nor were they ever.

I've got some questions on 96-98 Cobra cams. I bought a set off the Corral and I got LH cams.....

Now the first cam I got is this number which I believe is a 96-98 Cobra Cam:
F6ZE-6A271-AB

The second cam in the box is this number which I believe is a 98 Lincoln Cam:
F6LE-6A271-BB

Funny thing is, they are both for the same side! Lay them down next to each other, they look virtually identical, but I don't think they are.

Anyways, I'm going to call a local Ford dealership tomorrow to check the numbers, but thought I'd put it out here for y'all to respond to. What is that second cam out of? I've searched the Internet and came up with this:

RH intake cams basic eng. Number is always 6A270
LH intake cams basic eng. Number is always 6A271
RH exhaust basic eng. Number is always 6A272
LH exhaust basic eng. Number is always 6A273

So the matching cam I'm missing should be: F6ZE-6A270-AB

This sound right to y'all?

your not really going to see a difference looking at them, i went through all this a few months ago the only diff in part #'s are the last two letters, but there is no power gain in the cobra cams over the mark viii if that is what your trying to do. thats why i got comp cams. searching the part #'s even on the 4.6l crate motor from frpp which is a 320hp motor its the same cam, the heads make the diff in power. its actually odd that the 4.6 320hp crate motor with no intake, valve covers, etc., your standard crate motor costs more than the coyote 415hp motor complete with intake and everything just dumb. anyways if your thinking of cams, go comp or something.and you didnt mention what you already had, you wont find a part # different because theyre the same, waste of time.

 

[NetKeym]

I got my answer from a Ford dealership part guy. The part number F6LE-6A271-BB camshaft came stock in a 1998 Continental or Mark VIII which I what I thought and gathered from the internet. It is NOT a Cobra cam, which is what I kinda knew. I'm not starting an argument, but the 96-98 Cobra heads and Mark VIII heads are identical, the cams are only slightly different. F6ZE-6A271-AB Cobra cam is a .397 lift / 203@.050 cam while the F6LE-6A271-BB Lincoln cam is a .397 lift / 184@.050 cam. Nick over to modularheadshop has seen literally thousands of these cams, hundreds of heads, measured many many and can tell you about the differences better than me.

While I realize that an aftermarket compcam 268 cam is a .425 lift / 226@.050 cam and would be worth much more hp, they are also $1300 a set as opposed to the $150 I paid for the pair of cobra intake cams. This isn't the first cam upgrade I've done, but at $1300, THAT would be a first! lol

As for the FRPP cams, they are different too, I was just looking at those specs last night, but I'm not sure where I stuck that info.

It's ok, the seller contacted me today and can't believe he split up the sets like that and he's gonna make it right, so it's all good.

ive got a site 1075 delivered. and thats the 106100 i believe. yea i talked to dealers too that all told me different stories, but unless your motor is already apart and you've got c heads or better cobra intake your not gonna see much of a difference, but ive got a junkyard motor around just to learn more about the motor and its setup. back in the day when i used to be in my garage all the time building sb chevy 350's and 5.0 stang motors cam swaps were so damn easy, this is a pain in theasss so like i said dont expect much unless your just messing around

 

[lobird91]

96-98 Cobra cam swaps are worth 20-25 hp. I agree its only worth it if you have the engine apart anyway, but they do make good power and propery degreed and advanced will not give up anything down low.

-Alan

NO,they're not.96-98 cobra rated 305hp. otherwise it would have been rated accordingly.
98 lsc 290hp.
we've had this discussion a million times. unless you go to a 03 or newer head/intake combo,then yes 20-25hp. thats the current crate motor 320hp.you go right ahead and do what you want have fun, good luck as mr.stromberg told me once if you just look at the ratings as they came the proof is readable in english the preferred and approved language of america thank you, thats why the factory hp ratings are there. dead issue.sorry.

 

[lobird91]

You mean kinda like 03 Cobras being rated at 390 flywheel and putting down 390 to the wheels or 99 cobras rated at 320 that were actually making closer to 290...yeah let me go ahead and quote factory horsepower ratings. Go compare dyno graphs stock for stock a 98 LSC puts down 220 or less while cobras are closer to 270-280. That is way more than an intake and drive train loss, but you do things your way it seems to be working out for you so far.

Easy there Alan - lol. Yeh, I'm going to get some graphs to see the difference. I have a 95 LSC that I'm gonna get a stock dyno done, then do a few bolt ones such as CAI/UDPs/Fluidamper/Exhaust/Tune/few other tweaks of my own for a 2nd dyno.

Then I'll install the cams and get a 3rd dyno with no other changes; just a degreed in Cobra cam install.

no i know damn well the difference in flywheel and hp to the ground, and if youll go back and search the threads, as chris or laser would say to do before getting your panties in a bunch, the form of hp rating is focking irrelevant as long as its the same method. nobody's comparing flywheel to ground hp.anyways on this subject i thought the same as you did, wanted to do the same thing you want, i was told the exact same :q:q:q:q from the other members, as a matter of fact the specs are at the top of this year old thread as well as the others which is why its called let me ask again, the latest version after i was told the same :q:q:q:q from different dealerships and 94M5 was the first to say he "loves it when some guy comes on and writes 'thats what the dealer told me'." there are always going to be anomoles here and there and yes after getting told the (let me say it again) SAME :q:q:q:q im telling you by almost every member on here who actually laughed when i said "well the dealer told me this" the truth is still the truth whether you choose to believe it or ignore it.and it has worked out for me thanks.

I thought you have been having all kinds of problems with your ride?

 

[lobird91]

Oh I am plenty calm its just the internet
I have been in the mustang scene for over way too long and built way too many engines to worry about people who quote factory rated hp numbers. Just dont want other people to think the mark cams and cobra cams are the same. I have both and i promise you they are not. The mark cams are almost spot on to the specs of the 03 up cams.

No actually you have no understanding of what i want to do. And 99 percent of mark owners are not the be all end all of performance knowledge. And I dont go by what the dealer told me i go by actual measurements, they are NOT the same cams and you will see an increase in power with them.

my problems were not cam related.

listen alan, im responding to what you posted in gaining 20-25 hp increase from the cobra intake cams and it wasnt you it was netkeym who was talking about dealer whatever, and i am on the other side of the coin on actual gains when its been specifically discussed like this with like 8 people for weeks with documented answers just like the ones your claiming which make my point. will you see gains i never said you wouldnt just not that much, more like 10-15 which you can see on a graph, dyno whatever but you really cant feel that kind of increase and not to get anyones hopes up swapping out the cams only to be disappointed . its been done, logged,and posted
