E-303 idles mean as hell I thought it was a mild cam.
 

I thought my idle would be close to stock with the e-303 cam but it is pretty damn lumpy. Everything is set and tuned right on the car it is just alot more aggressive sounding than I thought it would be.

BTW: I do not reccommend this cam. It is a real PITA to get your car to idle without surging below 1000 rpms.

I had to drill a 3/16 inch hole in my throttle body flapper to get it to idle right. Anyone else have to do this?

I hope this cam performs well with my combo cause it sure was a BIOTCH to get everything right.

Later,

Are you going to have it dyno tuned? If so, a nice custom autologic chip can solve your idle woes.

Yeah, the 110* LSA gave for a pretty nice chop. I always got comments on my cam lope . I expected it to have a milder idle too.
I like my Comp XE 270HR a lot better, much more power in the middle and the idle has a much smaller lope.

Hey Dark
 

I know what you are talking about.
I opted for the "softer" LSA of the B-cam, but wanted the lift of the E, so I used 1.7 rr's with the B to get the E's lift.
It made tuning a lot easier. I love the way they sound though, mine idles at 750-800 and I always get some comments on it.

E-cam
 

yea i have an E-cam in my car and it sounds mean as hell....it lopes like a mad man.....i never had idle problems or anything like that ...just popped it in and ran great....much much more midrange power with 1.7 rr's.....later

I thought about going with 1.7 RR but with 2.02 1.60 valves and 54cc chambers I dont think I would have enough clearance.

I was told that the b was much more aggressive than the e. WHICH IS IT???



Oh,
Dark 5.0, I received the spacer yesterday. It's in great condition!

Unfortunately I can't use it yet. Overhead hood clearance has become an issue, but when I get a Cobra R SVO, it's going right on!

Thanks again

I run the B-cam with 1.7 rr's. It sounds nice, but like others I have trouble getting the idle just right. I kind of got sick of messing with it, so I have the idle turned up just above 1000 rpm so it doesn't surge. Sometimes the computer will kick it down to 800 or so. It sounds pretty mean then.

Re: E-303 idles mean as hell I thought it was a mild cam.
 

You thought an E-303 cam would be similar in sound to the stocker??!! :eek: Yeah, both the E & the B cams sound pretty lopey. I run the B w/ 1.72 roller rockers and love the way it sounds. I have my idle right around 1000rpms...maybe a little lower. It idles pretty smooth. Has anyone else had to drill a small hole in their butterfly of the throttle body?

I wasnt very happy about having to drill my throttle body but there was no other way.

I have heard e303 cams in stock engines and they didnt sound nearly as mean.

I think my free flowing engine and exhaust set-up have alot to do with how mean it sounds.

I like it now that I have it tuned right. But I damn sure cant get away with telling someone that its pretty much stock anymore:D

What crackhead told you it was mild? The lift is mild, but the LSA and duration show that it has a lope...I had it, hated it.

It IS a "mild" cam as far as performance goes. I commonly see B cammed cars performing better than E cammed cars on the street. Different power curve.

I never had any problems with mine though unless I ran A/C, but I fixed that because there were some busted vaccum lines coincidentally.

Did you disconnect the Idle Air Control valve to re-adjust your idle? Did you disconnect your computer so it could relearn everything? A cam is a big mod because it changes your a/f mixture.

The lope is cool, you will like it after a while....for me it actually wasn't lopey enough!

I was looking for a better than stock streetable cam and came across this e303 cam dirt cheap so I went ahead and threw it in there.

As long as I can run 12's and drive it on the street now and then I will be happy with it.

Yeah man of course I unplugged the idle sensor and reset the ecu.;)

I guess the dyno will tell the story.

e-cam
 

It is a pretty mild cam, if you guys remember i had a post about how i couldnt get my car to idle without surging/stalling?
That turned out to be the o2 sensors, also i had the idle set too low, now i have it idle about 900, sometimes it will drop down, and it sounds killer, i drive my car everyday, and havent had any idle problems since my old post.
Today my friend rolled up in his 93 gt with the new f-cam installed, that sucker was pretty lopey, made my car sound mild, but i think i can still whoop him:D

Dark5.0, it seems people that go to a bigger 2.02 valve aluminum head, and bigger cam, (like my friends 93) the exhaust note completley changes, that buddy of mine with the f-cam is about to get some turbo mufflers it's so damn loud:)
later......

I would have ran the F-cam but I dont think I have the clearance.

I may try putting 1.7 RR on the exhaust valves.

Don't Drill Holes In Your Throttle Body!!
 

Don't do it! Install an adjustable idle spacer instead. I put one on my lincoln last fall and have had no more problems setting the idle speed. There's one on e-bay for $19.00.

Have a geat day!

I loved my E cam it sounded good made good power and it was great for a daily driver. I then moved up to a trickflow stage 1 and it was very similar to the E cam as far as driveability and lope but it has a higher power band. I know have a B41 waiting to go in it should sound down right nasty.

Yeah the E-cam has a louder idle than the B or F cam. I think it sounds damn good. I put 1.72's on mine and it sounds real mean now. My car made great power from 2500 on up with the edelbrock intake and 1.6's on the E-cam. I switched to a systemax II intake and 1.7's and I lost a TON of lowend, probably a combo of both. I gained power maybe 300rpms higher than before. My car was dying off around 5600, now its more like 5900-6000. And now the power doesnt come on till about 3500, not nearly as fun. My buddy car has a TFS #1 and it just pulls and pulls to redline, but a little less lowend than my first combo on the E-Cam.

And yes its a ***** to get it to idle. My car idles around 1100 rpm now.

Whats the lift/duration on the TFS 1 cam? Would it go good with the Track heat intake and stock heads for now, and maybe eventually some twisted wedge/Track Heat or AFR 185's?

The trick flow stage 1 (off the top of my head) is 498 510 and 220 224

If you run the trackheat on stock heads run a 3/8 spacer to get some low end back (beause it is gonna be a mismatch with stock heads).

The F is a lopeier idle then the E....512 lift vs. .498 and 114 lobe vs. 112, and 288 duration vs. 284. I had a F and a E...the F pulls harder and lopes more.

Sky, I bet yours is louder because of the rockers...
