E-cam vs B-cam?
 

Dilema....
You see that I am putting a SQ blower in at this time.
I have had the B-cam for a year and like it's throaty idle but good driveability characteristics.
I want the lift of the E-cam in order to get 500 hp at the flywheel at 8 PSI, but I want good idle tunability and low speed behavior.
Does anyone have a E-cam or one like it on a daily driver?

specs...

b-cam(in now)
480-480 224-224 107-117

e-cam(thinkin really hard about it)
498-498 220-220 110-110

My latest additional parts include a 77 Pro-M, custom chip(waiting for cam specs), 42# injectors (I don't even want to think about detonation), and a MSD BTM, T-rex in-line.

Like I said this is a daily driver, I just want a 500hp daily driver.
(Doesn't everybody?)

I have had both. The E is in right now. I have speed density and have NO PROBLEMS. I even bring my daughter to school in the mornings before going to work. Sitting in that stop and go traffic does no harm either. I really believe that a custom or "blower" cam would be better than a ford shelf cam. Regaurdless that mass air meter will take care of you with what ever cam you want.

thanks
 

Appreciate the info.
I have every intent to look into a "custom" grind for my app.
Thanks again.

i have the e-cam in my cobra and it works great with the blower but for my coupe i chose a custom grind .525/.536 218/232 and i plan on supercharging it soon i think it's gonna scream.

TFS heads...
 

I like the lift of your cam but I have flattop pistons in my block with tfs heads so I have to watch anything over .535" and 235 duration.
Just checked this months MM&FF and they have a nice supercharged combo at 500 flywheel hp @ 8 PSI with a Crane cam that matches the mild b-cam specs.
Impressive, but I think that with an e-cam(or something with a little less duration and a little more lift) it might eek out 10 or so more hp.
Thanks again...

Hozer, your 88 should have flycut notches in the top of those pistons. As far as I know they are the same as '94-'95 except yours are forged and mine are the hypereutic. I have a e-303 cam with gt-40 p heads. I had to get a custom chip because sometime the idle would surge. After the chip it was fine.

if your heads have 2.02 intake valves i would go with the e-cam i'm sure your pistons have the same valve reliefs as stock but with 2.02 valves you have to be a little more careful still be sure to check your piston to valve clearance better to be safe than sorry.

How did the chip help your idle? I ask beacause my idle surges, and despite all my efforts to find vacuum leaks and replace emissions equipment, it refuses to idle well!

TRW Pistons...
 

I have TRW Flattop Pistons w/o valve reliefs in my rebuilt motor. I also have 1.7 RR's which limits my lift.
I believe the E-cam or something in that range with maybe a slightly different duration will be the one tha works the best.
As for the "chip", I personally consider it the best way to manage an aggressive cam and motor setup and maintain driveability.

Basically what would happen is I would start up the car and it the idle would jump up and down and it would idle uncontrollably. If I were to take off and drive it a block or two then come to a stop then it would idle fine. If I were to shut the car off for a few minutes then start it up it would have a difficult time starting. I would have to take the gas pedal and press it to the floor while rolling it over. It would then start but idle rough again. I called a place called, Auburn Performance and he told me it was because the computer has a difficult time running the cam. He sold me a custom chip and it made some other changes to the computer also. I put the chip in and it started right up and idled fine. Well it did idle a little rough but that was the lope of the cam :D I never had any trouble after that. I would highly recommend getting a chip. I am not talking about a hypertech chip either. I dont know how these work and as far as I know its a generic program. I had to tell these guys everything I had done to my car. They then made the chip of my info.

The AOD doesn't really like the E-303 cam. I have that sucker in right now, and sometimes while changing from drive to reverse it would bog or die. If I give it a tiny bit of gas then there is no problem.

I think it should be fine once I get my T5 in, but for now it is kinda annoying.

Great sounding cam, IMO though.

I basically have the problems you guys are describing. Poor vacuum at idle, horrible idle surge, and sometimes it stalls when I put it in reverse. How was your gas mileage before and after you got the chip? (my gas mileage is awful)

why choose the alphabet cams?? Theirs like a million different cam choices out there. Comp makes good cams, as does lunati, and others. B cam doesn't make that great of hp, neither does the E cam. after about 4500 the b and e cams are done with.

i like the e-cam i run it to 6200 in my supercharged cobra and it screams it's still pulling hard when i shift i need to get an rpm extender so i can shift at 6400 it's still pulling like mad when i shift.

Maybe it's not the cam you feel pulling. Superchargers are great up top on the rpm range..so i highly doubt it's the cam. The E cam isn't the greatest high rpm cam out there :rolleyes:

I wasn't saying it was just the cam I was just stating that for my application the e-cam works great in my coupe I have a custom ground cam and I have no doubts it is better than the e-cam but it also cost twice as much the e-cam is a good all around performance cam it gives you more aggressive lift and duration but still retains good idle quality.

I disagree, I think the E cam is a pretty good upper RPM cam. It sucks down low. On my car (N/A!...for now), the power band is from about 2600-5600...

Thanks,

That's funny because every mustang that i've ridden in that's had a E or a B cam has fell on it's face after 4500 rpm. And all these cars had intake, heads, full exhaust, big throttle bodies, maf's, etc, low rear end gears. So it won't convince me that it's a good cam cuz it's not.

Hozer Why not go with the stock cam? You'll find out with the S trim that you dont need a big cam to make the power you are looking for. You can make 550 at the wheels with the stocker and still retain driveability, and thats not even intercooled or overspinning the blower either.

I would seriously consider it.

I have the E cam. My car makes great power. Peaked at a little over 6000 rpm on the dyno. There are better I am sure, but it works fine for me.
