Cam Question... "F" vs "E" cam

doomsday255 · Sep 1, 2006

First of all, I have to say to everyone... I love this place!!! I have been reading through to forums for about a week or two and have found more information then I could have wished for. Its a goldmine here!!

Anyway.. I had a quick question for you all. I see that a lot of the people on here have used the FFRP "E" cam for their builds and produced great #s. I had no clue when I started mine and figured bigger is better and went for the "F" cam. Im wondering if im going to be able to pull off 300+ hp and if im going to have any extra problems by going with the more agressive "F" cam. Let me know What you guys think.

Thanks,
Jason

Welcome to the boards..

What heads do you have?

DMAN302 · Sep 1, 2006

300 RWHP takes a good collection of parts and a decent tune on an N/A 302/306 EFI car...cam selection is good part of the equation and F cam would not be toping my list. Head and intake selection would be priority for me.

Right now, all stock minus the .030 over bore and the "F" cam. Exhaust is aftermarket, though I'm not sure what it is. I know it takes a nice set of heads and really improving the air/fuel flow of the engine. What im really looking for is did I go too far with the "F" cam or will that be a workable cam for what I'm trying to do??

bone stock with just an F cam... kinda jumping in head first aren't you? from my questions over the last week or so... my answer to your questions is... F is way to big for stock heads and intake. you're not flowing enough air for a cam like that. Not to mention, most people aren't fans of the alphabet cams, but talk highly of the TFS cams...

DMAN302 · Sep 1, 2006

F cam is really going to start wanting to make power where the stock heads are looking to finish up. Likely what you find is the car soft down low and maybe a little more crisp up top..likely you'll be disapointed with the gains if you go in with big expectations. My guess is you'll gain a decent 10-15 hp over stock but mostly in the top end of the Tach. The .030 overbore nets you really nothing performance wise...but it sounds cool . Like I stated earlier heads and intake should be a priority..then find a cam with a power range that best suits the parts your have in place.

yellow1995Cobra · Sep 1, 2006

When you get heads on there im sure the f cam will be fine. The LSA of the F cam is actually higher then that of an E cam, so for our picky computers you should actually have less drivability issues with the F cam.

And before someone jumps on my case about the F cams LSA, its:

Duration = 226/226
Lift = .512"/.512"
LSA = 114* (109*intake/119*exhaust)

Where as the e cam has an lsa of 110.

MI95Cobra · Sep 1, 2006

me personnally i would go with the ecam, from prior experience with the ecam i loved it, it gave a nice lobe with my exhaust and i gained horsepower....with my cobra i'm going with an ecam or fcam, or maybe a crane cam with a similar lift to the ecam...

Back in 2003 or 2004, from what I can recall, MMFF compared various heads (AFRs, Canfield, GT40 Edelbrock, TFS etc.) to determine how they performed using a CHP 306 motor and a comp cam that had similar numbers to the F Cam. I recall them getting 399 HP at crank with AFR 165 heads and Carb (granted not EFI). Now with an EFI, you would get little less but never the less sitll good HP levels. I know I still have the magazine and will try and find it. Does anyone else recall this article?

I belive this is backwards, from what i always hear fuel injected combos always make more, to my knowledge carbed cars dont run near as accurate of a air fuel ratio and are usually running rich in comparison from what i hear, but i dont have any real world experience.

Some general thoughts about the alphabet cams.

They were made before we had all the choices of heads we have today.

From my way of thinking .............

That means Ford built those cams to crutch up exhaust of E7/GT40 oem iron heads.

Older technology cam for older heads.

Not ragging on the letter cams here and not saying they won't work with combos that have heads other than the older heads.

Peeps certainly have made good power with the letter cams.

But for my way of thinking ... I would at least consider if newer technology could be more beneficial for what I was trying to do.

As for Jason ... Seems to me he needs to think about what he wants to do or where he wants to go.

He already talks about wanting 300+ but is that rwhp or fwhp as there is kind of a diff

Like Jesse said ... I remember the f-cam as having a higher power band than the e-cam.

Again depending upon goals for the combo ......

If looking for 300+rwhp ...........

Jason could pick an intake like an RPMII or Track Heat that would do better with the f-cam for now.

Part selection along those kinds of lines would work great if he plans to step up to better flowing heads later. IMHO...Consideration of a cam that may be more suited to those heads would be wise as well at that time.

If a softer low end is the result with the f-cam

Jason could do the following to help without changing out the cam

advance the cam a bit
steeper gear ratio
lt's

Good Luck Jason

Welcome to 94-95 :SNSign:

Yes, when I started on the car... I didnt have a clue. I wanted to throw some better parts in the car and thats what I ended up with. I know I will be doing heads and intake and all that good stuff in the future. First goal it to get a Tweecer so I can really get this thing driveable!!

So far I'm thinking GT40P heads ported and Cobra upper and lower intake. Thats if I dont decied to go the Kenne Bell SC route

Oh and Grady... 300+, Gotta be at the wheels of course!

STANGateURlilSS · Sep 2, 2006

a cam that people seem to have forgetten is the steeda #19.. made for and designed for the 94-95 computer..

a great cam for use with 1.7s

so the F cam actually works well in our cars? or at least decent. how would you compare it to the TFS 2 cam as far as driveability issues?

legalize420 · Sep 2, 2006

i dont understand why people complain about 110 lsa. i mean, if you actually have experience with it and had problems i guess thats fine but most people go by what they read. i daily drive my car untuned and i have no problems. i did have hot start and a bad hanging idle problem but i solved them buy getting it to idle at 900 and the iac screw is only open 1/4 turn. its more of trial and error on the idle. you gotta find what works for you. it took me a while to get it like this but i am happy with it. just my .02

j/k jason get that thing rollin again

Every 110 lsa cam i had gave me issues as far as idling went. I had a B cam, and two FTI custom cams.. Took either a tweecer or custom tune to get them to idle right.

Five0- I do not have my car running yet. So i can say for sure how it will work out for me. But given the rather high LSA for aftermarket cams i expect the idle issues to be non existant. Ive never tried any TFS cam, only the 3 i posted above.. Main reason i went with an F cam in the first place is its raved about on tm.com for being a huge power producer with a turbo..

thanks for the response man. i see you will be using the F with a turbo setup? how do you think it would work on a NA setup? good choice/bad?

SeriousSN95 · Sep 7, 2006

ive got two turbos and the F cam is amazing. it almost feels like it was a custom grind for the turbos.it gave me way faster throttle response and also just makes the car sound like a monster idling. ive had great luck with it and i know someone whose running the same engine setup with the procharger and he runs the F cam. and he owns his own performence center here in daytona.

fawcett · Sep 7, 2006

My car idle sounds cool, the exhaust note across the board is pretty killer. Too bad my computer makes my engine cough its guts out.
Either way I dont see your car running great with out a solid tune. I'm getting mine as soon as I can afford it.
My car's drivability sucks balls, the idle is at like 1100rpms to compensate and keep it from stalling.
