E-cam vs B-cam?

[Hozer 88GTConv]

Yeah, I agree with the potential of even the humble stock cam.
Relatively speaking, cams are fairly inexpensive and everyone just wants the best setup for their combination.
I know the alphabet cams have positives and negatives, but they are pretty decent cams that are designed to cover a fairly large spectrum of combinations.
Are they the best? Of course not, because as long as your wallet is big enough, you can certainly get one matched specifically to your combo.
This has been an informative thread with interesting opinions.
I guess I have to decide soon. My supercharger is here waiting for installation as I write....decisions, decisions...

The E falls off. My shift light is set at 5800. Please don't tell my E that it's pulling to far. I was gonna set it at 6000. I'll wait

E-cams or the crane 2040 (same cams) Suck at idle unless you manualy set your idle to 1000. They are great for blowers and emission legal too. Love it and don't want any other unless I go to strip only. My car is a daily driver.

The b cam would be better than the e-cam for you.

The b cam is not the best for you, but I dont think your going to see the gains your looking for going to the E cam.

The e-cam has a narrow LSA which is not good for a blower car.

Look in the comp. cam catalog and pick out something with a 112-114 LSA, .500 - .535 lift, and 215-224 duration.

"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."

What Mustangs were you riding in?! Maybe a stock Mustang would have nothing after 4500 rpms, but a 302 with heads, cam, & intake that can't make power above 4500 rpms?? Those must have been some mismatched combos. I run the B-303 with Edelbrock intake & alum. heads with 2.02/1.60 valves. My motor pulls hard up to 6000 rpms no problem. In fact it doesn't even hit it's powerband until 3000-3500 rpms. Different combos work for different people I guess.

Same with me...but mine pulls til about 5800, but I don't have the guts to shift that high with my stock AOD with ~120k miles.

Also, it sounds like you are grouping the E and B cams together, even though they make their power in totally different places. I could see the B-cam dying on its face, because it isn't meant to make power up high.

Thanks,

Simi Stang, the cars i rode in had heads, cam, intakes, all the necessities for a mid 12 car. they ran good until they hit around 4500 then after that they fell on their *****. The best motorsport cam out there is the F303. My mom has it in her 95 GT and it pulls up to 6500. Has good low end too. I've never heard any good things about the B and E cams. Most people are dissapointed in them. Boys around here run big cams

Your Mom runs an F-303 in her stang?! That is awesome! Yeah, mine is not quite a daily driver, but still sees a lot of street driving. Is the F-303 a fairly streetable cam?

does your mom have an rpm extender on her car?

[eatsgmcar]

2 or 3 years ago, MM&FF has compared about 8 cams
on a dyno with the same motor. The engine has a common
head/intake combo and has free flowing components. The
B cam was far from the other cam.(+12 HP at the flywheel
over stock if i remember)

On the other hand, the e-cam was very close to big cams
that have 530 and more lift. The average hp was also closer
and more important the average torque was similar.(+16 HP
at the flywheel over stock when the best cam gave +18 HP)

I ve never had idle problem with the e cam since i have
raised the idle speed.

eatsgmcar-
How did you raise your idle? I saw an aftermarket adjustable idle kit for '86-'93 5.0s on e-bay for like $25. Did you use something like that? Or can I raise it without buying any additional kit? I think my stang may benefit from a slightly higher idle.

Believe everything you read, or do your homework and make your own conclusions. The choice is yours. The e-cam is not a preferred blower cam.

[Eric4Nitrous]

Yes bigblock she does have an rpm extender. But it still pulls hard up to 6500.

I posted that for verification that it is indeed a blower cam. I have done my research and it was the best choice for my application. And I hardly believe the guy who built my engine would allow me to make a big mistake like that. Or better yet you can run me and I'll show ya how well it works as a blower cam.

[Eric4Nitrous]

I'll run ya..and show you it ain't a good blower cam

my point exactly. Thanks for verifying my suspicions. You posting that doesnt verify crap. The e cam is not a good blower cam, and Eric4nitrous has got my back (thanks bro).

You may think its a good blower cam because your car runs well with it, but what car doesnt run well with a blower?

Whys is it a good blower cam? Back up your smack with some knowledge. Because you read it somewhere? Lol...later...

[Unit 5302]

Sometimes I wish I wouldn't even look at this site. The BS in this thread is so deep I feel obligated to post.

Eric4Nitrous, please give some credit to those posting on this thread that have the cam you're talking about. They may not have $40k to have a builder make an engine for them, but they know what the heck they are talking about, and you sir, have no clue. Take your 6sec car and race it or sell if for all I care. Bottom line is I won't tolerate your bull on this thread. Do a little research and figure out how cams work. You don't even know how a camshaft works, obviously. Even the stock cam will pull to lower 5000rpm ranges when installed in a mildly modified 302. The manufacturer rated power ranges on both the E303 and the B303 extend to 5500rpm+. I don't know where you got your high horse from, but it's time to start letting Mr. Glidden answer your engine tech questions.

Mach 1 You seem overly concerned with LSA's again, but unlike your assistant in misinformation, you at least have a good idea of camshaft basics. As I have pointed out before, LSA's are only one part of camshaft overlap. A snapshot of the E303 looks like this.

.498/.498, 220/220@.050, 282/282, LSA 110, LCA 107/117

The B303

.480/.480, 224/224@.050, 284/284, LSA 112, LCA 109/119

What that all means? The E303 when installed straight up, is not actually straight up. It's built with a 3* advance on the intake to help control compression. It also has a less aggressive ramp rate than the B303, and less duration. That means the actual amount of overlap on the E303 is smaller than what you think. That's why the E303 is recommended for the AOD, and the B303 for the 5spd. The B303 has the makings of a more high winding cam than the E303, but doesn't have enough lift for an EFI car. The B303 will perform well on a carbed car, though. Not that it's BAD on EFI, just could use some more lift to make use of it's more aggressive duration.

The E303 is a solid supercharger cam. Both you can Eric might learn a little by checking out some of the site's combo's using the setup. Nicolle Douglas is making 500rwhp with an E303 and a supercharger. Dan McClain made 500rwhp with a supercharger and E303. Exgmguy has posted here about how his combination runs. Skyman's car peaks over 5000rpms as well. 88workcar has posted. What else do you skeptics need? I've given a technical analysis, as per standard, along with some explaination, and cited examples of people running the cams you're bashing. I fail to see how you have a leg to stand on. Not that you had one before with people who ACTUALLY run the cam telling you it works. Mach, I do believe you had the E303 in your auto at one point, and you were very frustrated by an idle problem common to the cam. Maybe you're harboring grudges for it robbing you of sleep?

[Eric4Nitrous]

Unit just when i think you've said something stupid..you keep running your mouth. Ok so YOU know everything about how to go fast huh? Looks like you don't know your head from your *****. If you did you wouldn't have a 14 second car. So your not gonna tolerate my bull on this thread?? what are you gonna do ban me? Now i know why you were voted MW's PITA. It obviously shows. Go read some more magazines and then come back to me when you wanna talk about going fast.
