I've got the E because it's supposedly street legal, but the F should be a strong runner also. If emissions are no issue, i'd say the F will probably match up the RPM heads a bit better.

Agreed... why alphabet? Why not custom grind or choose something out of a catalog to better fit your combo?

Tons of cams to choose from... Ive used the Lunati 51014 in the past and loved it..Adv. Duration: 284°/292° Gross Lift: .500"/.510" RPM Range: 2500-6000. I ran this cam with a 4 degree advance and a set of edelbrock stage 2 performer heads... 1.94/1.60 valves from bennet racing along with a Performer (not RPM) ported intake. It made 315 rwhp 342rwtq and ran 12.20s in my 92 GT.

If he has RPM heads id assume they are the 2.02 valve heads... the 51014 lunati cam may have a clearance problem with stock pistons as my 1.94 valves were extremely close.
no there 190 valves. so the f cam wont work well not even with it being a cobra?what cams will work well?no the car is not daily driven i run a 125 hp dry system my futer plan is an ati procharger in 2 months just using the spray off my old car for now thats were my heads came from two it was an 89 gt 11.40 at 118 with the same heads that are going on my new project 94 cobra

Id go custom grind if I was going to be running that much motor.. I just read up and the RPM version just means it doesnt have the emissions ports.. now the 1.90 valves would clear fine with the lunati 51014 cam but im not sure how good it is for power adders as I didtn see the lobe sep.
Back to this computer issue. Why will my cobra computer not tollerate a larger cam? Is this just the f cam or all cams ? How long does it take to get a custom cam? Were should i call? I want to make the MUSTANG shootout at my local track so time is kinda an issue but hp is more important in the long run. any other opions ?

The SN-95 computers are a little more picky than the fox A9L computers when it comes to cam swaps. Whatever cam you go with you're going to need a chip or tuning device. It took me two weeks to get my custom cam. One week to design and grind and the other to get to my house. I went with www.flowtechinduction.com. Send Ed an e-mail and tell him exactly what you want and your combo and he can whip something up for you.

The F is not good for superchargers. The alphabet cams are NA cams. A supercharger wants a wide LSA, dual pattern cam. The F is neither.ProKiller said:
The SN-95 5.0 computers are much less tolerable of modifications. I'm not exactly sure why though. Cams with a shorter LSA (< 112) do not provide as much vacuum as a cam with greater LSA ( >112), which may be why they tend to wack out with a good NA cam. If you plan on getting a supercharger, you might as well get a blower cam, since you are only going to be Nitrous/NA for the next few months. A good blower cam for you is something with a 114-116 LSA, a 216-218/220-224 duration @ 0.050 and a .520-.530/.530-.540 lift. Look around and see what you find. You probably wouldn't have too much of a problem, if any at all with your computer because you are looking for a wide LSA and short(er) duration cam.

First off thanks for all the help guys Im fairly new on here.Can i really run a 5.40 or 5.50 cam with stock pistons ??? I was under the impreshan 5.20 was about it .My heads have been milled some and may be again i will find out in the morning. As far as the computer goes would an Anderson pms solve my aparent soon to be problem? ANY ONE FROM PA. MD. ON HERE??

My cam has over .550 on both intake and exhaust and is *suppose* to work fine with the 1.90's on my AFR's. Duration is a big factor in piston to valve clearance though. The PMS will work fine as a tuning device. Send Ed Curtis from flowtech induction an email even if you don't plan on buying a cam from him. He is very helpful and will swing you in the right direction for your combo.

It's not the lift figures that are the problem, it's the duration - how long the valve is held open. You can run some .630" lift cams and not have a problem and you can run a .430" lift cam and have problems. It all depends on duration. How much have your heads been milled? They couldn't be milled that much, because after about .040" have been taken off, you've got to mill the lower manifold too. Just be sure to check PTV before you turn the key. It would also be a good idea to talk to someone from Comp or Crane or where ever you buy the cam from, and see if they think you will have any PTV interference. I would hold off on the PMS to see if you have idle/surging problems. It's a great thing to have, but it's certainly not necessary. I truly don't think you will have any problems if you keep the LSA to a 114 or greater. G'luck.FEESER 94 COBRA said:
