i need to find a cam for a 2.2l for a 02 cavalier so if u can let me no a web site that be great thanx
speed kills save lives drive a honda
no the take from the low side
my kill list:a geo metro and a mac semi wow did i kill that thing

Your best bet is to get a cam from a salvage yard and have it reground by your favorite cam company.
Sadly, that's not an option at this time. And I have a feeling that my favorite cam company may never be the same. <sigh>
Madjack, have you ever looked into possible differences between smallblock and bigblock cam lobes? Maybe there's a little more to be gained from a different profile?
With Crane Cams being sold off, I've been trying to collect some of the tech articles and catalogs from the web page. Is there an active link to the cam lobe profile catalog?

This is such a joy to read. MadJack: The remark on how the exhaust can do with some favor on the duration is just what I was thinking the other day. I was looking at the Comp-Cams Thumper-series cams for the SBC & realized that the profile combined with a LSA/LDA that such a profile would be perfect for the '98-up LN2' smaller exhaust port. Also, Thoughts of regrinding a '96-'97 cam to the same duration as the '98-later cam with slightly higher lift specs that also minimizes the width of the overlap, and favoring the height, used in conjunction with long-runner intake & exhaust manifolds (Header!) may be the way to go for me to build an engine with a torquey low-end for my '99 S-truck... to achieve the efficiency goals I have in mind, that is. Hmmm... Maybe I should reduce the FDR or add a Gear Vendors overdrive tailshaft-unit while I'm at it, to help keep it in the range.
Go beyond the "bolt-on".
some incredible things can be done by a good cam shop. i ahve a place in new hampshire regrind our stuff. he is a one man show and is very concious to quality of his products, Northeast Cams

Silly me. I went looking for a cam lobe catalog under the "Catalogs" heading. Just what was I thinking.
The larger base circle of the BBC cam allows more agressive ramps with flat lifters. While we're not looking for anything too wild, it's probably worth a study to see if a flat tappet BBC cam that "works" can be translated into a roller LN2 cam. Since many of the older cams were refined on a dyno by a "real" person it's possible that there's characteristics of a BBC head shared by the LN2 which are helped by a slightly different lobe shape. I've gone through the same thing with my Buick big block. Many companies just grind the SBC lobes onto the Buick core, but there are Buick specific grinds which will make more power.

yes he is in northwood, give him a call, i cna find his number if you need it. my race cam which again is falt tappet has a sbc grind on it
hot damn MadJack, I'm gunna be keeping I.P.P. on my contact list. that's a decent price for a cam to have been just made like that.

I hear that, about how most cam grinders... even makers, for that matter... tend to resort to SBC lobes for the design of the cam; even though it's meant for a non-SBC app! I mean, c'mon... Chevy lobes in a Mopar!? That's so incorrect.
You do bring-up a good point about how perhaps using a lobe... maybe even cam... profile like found in BBC-apps. I wonder what the LSA/LDA on those are like? Probably the same or very similar to those used on the LN2's bumpstick. If so, there's a lesson to be had there. I mean, since the lobes are (as I've found)
very similar in shape to those found in the '87-'95 GM truck/van TBI 350(5.7L) V-8... doesn't it make sense to apply lobes found to be advantageous in that engine to our cams? Just saying...
Go beyond the "bolt-on".
IPP doesnt offer that cam anymore, I called them like 2 months ago and they stopped making them!
I have a turbo cam regrind from Comp Cams if anyone is interested!
PM ME
NOOOOOO!!!!!!!!!! dammit, those were somewhat clost to what I was looking for for the Cam.
the Cam you have, I may want it eventually, but I won't be going turbo for quite a while.
Did anyone see what I posted!?
I HAVE AN EXTRA CAM THAT WAS ALREADY RE-GROUND!
I heard you, pm sent.
When in doupt, grub.
Just learned something: Remember my question about BBC LSA? Well, I just learned that they ranged from 114* (Base-model workhorses) to 110* (High performance models). That explains why the pre-'97s have such a wide separation with a lobe shape reminescent of those found in the '87-'95 truck/van TBI 5.7L V-8: The head is so-much like the oval-port BBC head that only a cam designed with the separation of one meant for the would work. At least that's my theory....

Lost me there.
Pre-97 BBC? Changeover was in 96 to sequential injection.
Pre-97 LN2? Changeover was in 98.
Are you saying the cam in the 92-97 LN2 is like the cam in the 5.7 truck because the ports are similar? 5.7 tbi is smallblock, siamesed intakes, swirl port head while the tbi big blocks from 88-95 had super-small "peanut ports" that breathed about as well as a lung cancer patient in the final stages of life. Neither is much like the LN2 in terms of intake port volume / cylinder volume ratio.
I'd expect the mystery of the sbc lobes on the LN2 cam lies in design and manufacturing costs. So much of what GM did in the late '80s and '90s was shared among different platforms to save costs that this just falls into the same pattern.

I meant in lift & advertised duration, the "Series-I" LN2 (Let's just call the pre-'97 LN2 that from now-on, shall we?) compares to the TBI SBC cam. And the LSA/LDA is like that found on a BBC cam. And you don't hafta tell me about cost-savings had from sharing... I'm pretty "tuned-in" to the way auto-manufacture corporations think. Hence why I saw that the return of the "Ute"-body to American production seemed unlikely, unless they slate it as the only body-style that a 1/2-ton chassis model will be available in when full-size trucks go to fully unitized construction. Or drop the current compact-truck line to make a lower-cost 1/2-ton compact-truck that also meets impending safety regulations. But I digress...

Pre- 98 LN2 is the correct description. The change happened with the '98 model year.

What do you call the 3-4 LN2 variants that came before? Series 1/4, series 1/2, series 3/4??
