CAM question

I presently own a TFS-1 CAM and I’m rebuilding my motor as some of you know the question is I could get an E-CAM for nothing. Might it be a better cam for what I’m doing my basic set-up is going to be stock E7 rotating assembly GT40 iron heads 10.1 compression GT40 explorer intake 70mm TB and mass air. I know most would say the TFS-1 is a no-brainer and I agree but what I’m wondering since the I could get the cam for free and the mostly stock ford build might I see the E-cam being better for me.

I know the TFS-1 cam comes on at 2000 rpm, when does the E-cam come on this might help my decision since I’m probably going w/a 2800 stall converter.

Hard for me to say since I've never ran anything other than stock and my TF cam...  The E should probably give a bit more low end, but I like the nice little rumpty rump the TF cam has...

 Do you think 2800 stall is enough for the tfs cam?

I'm thinking the e cam will extended the rpm range up about 250+ rpm and give a little more top end from 5000+rpm from the extra duration and tighter lobes. The heads may run out of power before that. On paper the tfs1 seems like a better cam with a broader power band.
For my next build, my choice is the e cam or the crane powermax 2031. The power max is almost identical to the tfs on paper but for use with 1.7 rockers. Both of these require mass air.
If I stay speed density, the comp cam fwnx264hr14, would be a good choice, butmight be borderline on the map setup.
 Do you all think I should just go mass from the get go?

 Thanks,
 Mike

I'd say it's about the minimum... I run a 2600 and keep wishing for more...

Go for the Mass air...

Mine pulls hard to the 6250rpm fuel cut out of the EEC... I'm sure that's well past the peak but it never feels "run out"

This is what I'm going through.I'm wondering if the low end is any good with the E cam.I have one coming to me.I'm undecided whether or not to use it.I really want my low end power.I like the higher end power as well,but I don't see that very often.

With almost any factory head, you need a dual pattern cam, such as the TFS. The exhaust side of the head doesnt flow nearly as well as the intake, so that it needs a little more lift and duration than the intake.
It's Gumby's fault.

First of all, the E-Cam has less intake and exhaust duration and less overlap than the TFS-1, so you haven't even characterized the comparison correctly. Please don't mention advertised durations because they mean absolutely nothing.

TFS-1 221,225,.499,.510,112,1 degree overlap @ 0.050

E-Cam 220,220,.498,.498,110,0 degrees overlap @ 0.050

It's a no-brainer in my opinion - the TFS-1 is Trick Flow taking the generic E-Cam and optimizing it for the typical Ford head that has a poor flowing exhaust. With the faster ramps (shorter advertised duration versus longer 0.050" lift), you will have the same or more vacuum even though it has more overlap at 0.050" where the airflow starts happening in any appreciable amount.

The heads I have are factory heads that have had the exhaust ports opened up and a 3 angle valve job done..Do you think the E cam would be a decent choice?And,do you think that it will give decent low end performance?I am not building a race car,just a strong daily driver.

Not sure if you're asking me, but I've simulated these cams with a very good engine simulator on similar engine setups and the most HP difference you will see between similar "small" cams (TFS-1, E-Cam, Crane 2031, Comp XE270HR, Crower 15511, Anderson B21/31) on a restricted airflow engine (small heads/intake) will be 5 HP typically, maybe 10HP worst to best. Since each engine is set up differently, making a blanket recommendation is extremely difficult, suffice it to say that the diffference between similar small cams is small.

I wonder if I should just leave the stock H.O cam in,or is the E cam aworth enough to swap out.I don't expect a ton of power from it,but any improvement is good.Do you have any idea how well the cam should work on an H.O engine with a really good exhaust,Explorer intake,65mm t-body,and the ported factory heads.Is the cam too much for this engine in your own opinion?

Since you're going mass air anyway e cam or tfs1 would be great. I'm just not impressed with the factory ho cam.
IMHO, a great all around street cam is comp cams fnwx264hr14. If it works half decent with speed density, it should work great with mass air. Plenty of torque with some room to grow. Board member, chrome302jr is running it.

I wouldn't mind having a different cam,but,I'm wanting to use what I have (if the E cam is worth the time) because after buying all of the Mass Air stuff,roller rockers,etc,by budget is going to be small for some time.That's why I was wanting to know if the E cam is a good all around cam with some off the line power.

E-cam will do you decently on the street. I guess the bottom line is, theres always a better cam out there for you.

A lot of guys love the E-cam, but i feel that its just one of those "quick fixes"
It's Gumby's fault.

I don't want anything radical.I want good performance,and decent gas mileage.Nothing more than that with this car.If it was only a weekend driver,then big cam,and much more would be great.Since it's almost a daily driver,I need it to be a good all around car.

An E-cam wouldnt do you too bad. Its not optimal, but it is a good bit better than the stock cam. An old trick is when you buy roller rockers, get a set of both 1.6 and 1.7's, use the 1.6's on the intake side, and 1.7's on the exhaust. Then sell the rest off.

I found my set of 1.73's on the corral for 150 shipped.
