get the G5X3 114... end of story

 

949 was with REV springs... after breaking a million Lou stopped selling them... the comp 921 packages with pushrods are MUCH more

 

Yup thats me. Sticker slowly fall off there but its not bad so its still there.

Im shopping for a new project now.. maybe go with a 382 stroker kit and heads and cam in the far future hahaha. But yeah i wouldnt mind coming over to the meets in austin. I just recently bought a ford 8.8 rear end and im trying to get it install and summer school just started so it might be a while.. hopefully ill be done with everything this week. If your interested I could get my dyno chart over there too while im at it.. might just be a while hopefully 2 weeks the most cause i wanna test those 373s quick and im being a little impatient

add me if you use aol IM me at: ahmed9399

 

As I couldn't do it blindly, perhaps could someone PM me X2 specs.

At the moment i'm looking at TSP 225/225, .589/.589 112+2 lsa. Is the X2 much bigger than that.

Is the X2 bigger than a 231/237 ??

Better yet is the X2 or X3 close to a T-Rex?

 

Thanks! I think I finally understand!

Why is it though that with the X3, you can't do a 112, but with a X2, 112 isn't a problem?

 

will Crane Dual Springs be ok w/ this x3 cam on 114? it says good to .650 lift

 

no. not enough seat pressure. go with the 921's.

 

232/240 .595/.608

 

Ah so No wonder it likes to be sprayed. Heck with 8 points diff. in duration your only limit would be can your block take it or not and of course how good you are at tuning.

I can see now why it works well with stock heads + headers.

 

Now I am trying to decide between the x2 and x3. From what I have read and seen there isnt much of a difference between hp/tq gains with the two, am I correct? The x3 just has a longer and quicker powerband than the x2 which is more of a kick in the a$$ than a constant push? Am I making any sense?

Basically, with my mods in my sig, and flps to come (and the absence of heads for a while), will I be able to pull off numbers in the 400 range with the x2?

Everyone who has the x3 seems very pleased, but I am scared of a big cam for obvious reasons such as money for a new engine Still a little scepticle.

I think its funny how some of these guys are so "into" the G5X-x cams but dont know the specs??LOL. I promise SSonMySix, the G5X-3 is very very close to the X2...it has to be or it wouldnt fit. There isnt enough PTV clearance to make huge changes...Lou himself even said that they are very close. Sure it makes a little more power, but to make people believe its a different animal is just not the case...no I dont have it, but I know plenty about cams to know what makes a huge difference. I'm not doubting that they are both excellent high rpm performers..they definitely are...but to make people think that they are good street cams for most people...just not the case.

 

Who said I didnt know the specs

edit- And why should anyone care what the specs are? How many vette & Fbody guys do you think drop off their car at MTI, or Thunder, or anywhere else and just say "Make it fast" and dont ask questions... Lou says it works... many others say it works... that should be enough.

One of my favorite quotes... "You know, you can stick your head in a bulls *** to see what the meat looks like, but wouldnt you rather take my word for it? "

 

On a side note, I do think I am a LOT more informed on these cams then yourself 1) because I have run both the G5X2 and G5X3, 2) because I sell and install on average 5 of these cams a month, and 3) because I talk to Lou on a regular basis and he answers EVERY question I have about these. They are 100% daily drivable and DO NOT CAUSE ANY DRIVABILITY ISSUES. I have people ranging from 17 year old kids to men over 50 that are running Lous cams... I even have a handicapped guy driving one of my G5X2 cars... Theres nothing wrong with the cams, and It honestly bothers me how all the LG haters can bag on the cam and say up and down how much they know about them, YET THEY HAVE NEVER OWNED ONE.

Just simple facts for you...
1) The G5X2 and G5X3 are DAY AND NIGHT different... not a little... A LOT
2) the drivability is AWESOME in both cams, EVERY ONE I have done has idled fine, ran the air conditioning fine, worked in auto cars etc
3) PTV clearence is NOT an issue with these cams... Lou states not to run the X3 112 to everyday cam guys to save his ***, which I would too... No point in having people do the swap, then do a 3-2 shift on accident and fry the valvetrain
4) If knowing what your cam specs are make your car faster... then I guess EVERY customer I have is slow because not one knows their specs, and you know? To this day not one has bitched about not knowing, and honestly I dont think they really care. They are fast, they make a lot of power, their car drives awesome, they get good mileage... I could tell them I found their cam in a junkyard and just tried it to see if it would work and I bet they still wouldnt care BECAUSE THEY ARE HAPPY!

im done ranting!

 

Good call SSOnYourSix. I completely agree with you on that. How can someone who has never owned either the x2 or x3 say that there are driveability issues. They probably heard from someone that they were bad cams due to someone having a crappy tune. Like any cam tuning is the main issue when it comes to drivalbity

 

Well thats the way this forum seems to work... you have thousands of members... 80% have never done anything more than change their oil... IF that, and they read a few tech articles given by people of similar mechanical knowledge, so they take that info as factual and think they are now educated on the subject enough to give advise... In reality it is nothing more than another uneducated (mechanically) person giving their 2 cents on a subject they know nothing about. So while a person has pages of proof to back up their claim, in reality all they have is a large amount of guessing and opinions from people that really have no clue in the first place... I have yet to see one G5X2 or X3 owner bitching about their cam or its drivability, HOWEVER there are plenty of NON G5X2/X3 owners saying the specs are too big, or the drivability sucks etc etc... PEOPLE - you cant just look at a cam spec and figure out how it will drive, how much power it will make etc... there is MUCH more to it than that!

Sorry "Forum Techs" are a big pet peeve of mine

Edit - mechanically uneducated people dont bother me... I LOVE answering questions, however people with no automotive or mechanical knowledge that try to tell everyone how it is are the ones that get to me... I will answer stupid questions ALL DAY LONG without bitching... but as soon as you start shouting out claims without any sort of proof I Get offended!

 

SS- I wasnt trying to start a pissing match here, just raising some valid points...Just wanted to let you know that I've done more than change my oil, LOL. Give me a little credit here ok, I'm no backyard hillbilly mechanic.

1.) PTV is not an issue on a G5X-3? I'd say .070" clearance is pretty damn tight. Sure it fits, but theres no room for error and if I wanted a ***** out cam, I'd install one without question. I just stated that its so tight that a 112LSA version is borderline able to fit.

2.) So what are the actual specs of the X3 if you know? If there are large differences, I'd expect 3-4deg duration differences in IandE and a change in ICL also. I wont tell a soul Either that, or someone needs to cam doctor one...I dont want to "steal" the specs, I'm just curious what they are. Funny though, last summers bandwagon was the X2, this year its the X3!

3.) What makes you the expert just because you "install" cams? You sure jumped to a lot of conclusions when you dont even know me.

Thats all,

I have no dispute in your experience and knowledge, however that is not a very rational statement.

Why would i want to know the specs?
Well for many reasons, to name a few:

1- The stock bottom on an LS1 is definately not designed to go over 6500rpm reliably. Stretching rod bolts, no crank journal oiling galleys etc..

2- As a racer I want and need to know what and where my powerband is, don't let my sig fool you, this is my 3rd LS1.

3- I'm a spray addict so the amount of duration split is critical to judge how much I can spray and so is the lsa.

4- I match my heads to my cam and not vice versa.

5- Not to look like a dumb *** when someone asks me what are my cam's specs and my answer would be "It's BIG, Lou said so"

6- Off the shelf cams are generics, so for a specified application you can get a custom one based on the generic item but more tailored to your needs.

7- A "Built motor" is a marriage of complementing parts, need to know how they work to match them.( I've gone as far as to tailor my cam to match my shifting needs in order to stay within 2% HP from one shift to another, meaning less than 10 rwhp loss between shifts)

To me, hiding specs is kids play. If the competition wants to copy bad enough, all they have to do is buy one and measure it. A few data entries in the grinder PCU and voila, exact duplicate.

To do it wisely, I would recommend at least a nitrated crank and ARP bolts with treated pistons for the X2.
Anything less is a timebomb, as stated before this is my 3rd LS1, and the only one still stock. (Well almost)

 

That's where i'm at. This is my 2nd LS1 and my 3rd Camaro. I try to learn everything I can before I dig into stuff myself. I've never gone inside a motor before, so that's why i'm asking pretty basic and stupid questions. I figure if I don't ask, I won't know ~

Ignorance is the worst form of stupidity (nor does it ever settle a dispute).

PREDATOR - Z:
That's 100% how i'm feeling about not knowing the specs. Sure, I might not understand the numbers at the moment, but I sure don't want to be that guy that says "I don't know, but it's big!". Kinda like saying "Yeah, I gots me one of dem der tree-quarter cams." At the very least, a cam card should be included upon the purchase of the cam. No excuses.

 

1) 112 isnt recommended for your everyday racer... and Lou states that, however it does fit... Will I install them? Usually not... unless its a special customer or one I get to watch over closely. I prefer the 114 for my own personal safety.

2) its a bandwagon because its everything everyone asks for in a cam... In addition Lou has given me the best customer service ive ever recieved from ANY company that I deal with... and at the first hint of a problem, whether his fault or one of his suppliers, hes on the phone getting the parts overnighted to me! As far as the specs go, im sworn to secrecy But as I said before, theres a lot more to a cam then the specs... if it was that easy then other companies wouldnt care about his specs and they would already have their copies of the cam that outsell Lou.

I was making a general statement based upon what I do know... and trust me, I do a lot more than install cams... But simple facts were A) you dont own a LG cam, B) you know little about the LG cams other than what you have put together, and C) you criticize the LG cams for no reason other than jumping on the LG hater bandwagon... If Thunder gave me a cam that could do this you bet your *** I would use their cams instead... but ive been removing TR cams for the LG cams, which is why im biased. Show me a better cam and have me install it, if im pleased with it, you can bet your *** I will use and sell a million of them...

 

On a few rare cases where you are matching in that manor then yes, cam specs can help... however for the other 90% tossing this cam to stock heads and bolt ons, they are irrelevent. I have honestly not told one customer the specs on this cam, and I still have a mile long line of customers waiting to get their hands on one. People know what they want and have a number in mind on how to get there... I just show them the best route to take. Now when customizing components where measurments are crucial, and piecing parts from various manufacturers together, then I agree that knowing the specs is required for each part you are sourcing to work together... Then again 9 out of 10 times that is also left up to a shop though unless you are doing all the building yourself.

As far as the stock bottom end not going over 6500, tell that to GM that lets the Z06 go to 6600 and make sure they know that they have no clue how to build cars. I will agree the 98-00 cars do have weaker bolts, however even shifting at 6100 rpms... if you drive the car hard it WILL blow up. It doesnt matter where you shift.
