I know there was a limited amount of these produced and they require some valvetrain mods, does anyone have the full specs on them and are they still available, I'm concerned that I might be waiting too long to get my hands on a set of them and to date I don't know of another cam combo that works. I would think something designed by GM would work a bit nicer than anything else out there.

 

Search a couple of the threads area47 has made on them the specs are inside.

 

better yet is there someplace to still get the gm cams

 

gmtunersource.com

all the info is on there.
.....

 

ah forgot about that place, whats this you mention about needing valves seated or machined or some **** in the classified ad you had up

I was looking at that overthetop performance head with the oversize valves and upgraded springs would that work with no other mods with these?

 

comp cams makes them, gmtunersource has the downloadable .pdf of the buildbook and the specs on the cams are in there. i'm sure if you call up Comp they could hook you up with a set.

i'd give you the specs myself but i'm on the work computer and the .pdf is on my laptop.

 

Intake Cam: 0.441 inch net lift
218 degrees duration @ 0.050 inch lift
109 degrees of seperation

Exhaust Cam: 0.437 inch of net lift
220 degrees of duration @ 0.050 inch lift
109 degrees of seperation.
Straight from the build book.

 

^boom! there ya go!

 

I emailed comp and they said they did NOT make them... of course I could have just got an idiot

 

Build book says they were, but could be a typo or something. Plus they were a limited run of custom cams. So they may tell you that they don't produce them, because they don't. Only the limited run for GM-Racing.

 

True but he said that they never did, but he could get some just like them if I had the specs...

Although, I'm almost positive they did and he just didn't know what he was talking about.

 

There has been reliability issues with these cams combined with the stock lash adjusters. GMR uses bates engineering lash adjusters, machined to match on each valve. Jesel also offers solid lash adjusters in 3 different increments. An aftermarket company (don't remember the name) is now selling adjustable lash adjusters, but I have yet to see a review on them.

 

I could believe that. But yeah, with some blanks and the specs you could have them make up a set for ya.

 

summit has the full selection on comp cams with ranging lifts and durations that will fit 2 liter cobalt depending all on what you want. but remember if you replace your cam replace your lifters.... or in time you will break your ****. if you want some real power deck the block and get some wedge pistons or concave pistons is you want to lower compression and get some more torque. and polish your head(mainly combustion camber) and a 3 point valve job or even a 5 point. then you'll be making some serious power

 

thats for the 2.2. the hex key on the exhaust cam is not there for the lsj engines.



comp did grind them. you won't get the info out of them. you are not with gmr.

rodimus. valve springs, seat locators, ti retainers. supertech 78lb kit.

 

Would comp still grind a set for you if you gave them the specs though?

 

maybe.

 

Give them a call and find out. Be very specific and please let us know. I'd be interested in a set possibly if you need a small group of people in on it.

thats what i was looking at with the supertech valves and springs, would that run these?

 

E-mail sent to comp cams about making a new set of cams with the gmr cam specs.

 

rodimus. yepo. the 78lb kit would be fine.

 

so i wouldnt need any further machining?

 

I also didn't mention that when they said they didn't make them, I asked about regrinding stock cams to those exact profile and they have not responded (its been over a week). All they said was they were sure they "had something similar"

 

I got someone that can help me with the head swap its just im not good with trying to install a valve train and all that i want a bolt on head that i can slap the gm cams in there then start tuning

 

I really hate to say this, but, any of you guys with stock heads are just wasting your time looking at cams if you haven't got any porting done on the exhaust side.
