G5X3 Cam only...
Can you run a G5X3 cam only on stock LS1 heads (of course changing the springs, locks and retainers???
The lift seems pretty high - but I like the stated 70HP increase LG talks about...
Thanks!

Buy the kit from LG, and they will provide you with all the parts you need.
But at a minimum, I'd look at a set of good pushrods, and a either something like a PRC "gold", and Comp921, or something equivilant. I'm sure LG has a preferred spring.
If you look around you'll find plenty of fast cars running this cam.

I ran the G5X3 on stock heads with crane 921's for about six months and it was fine but I decided I wanted more so I had LG install a set of AFR 205's, FAST 90 and 90mm TB. The X3 is outstanding just make sure you do the springs, give LGM a call they'll steer you right.

basically chasing my tail....I want to go with a moderately aggressive cam but of course I don't want to have to rip into the rear or the tranny at the same time to either do a torque converter or major internal work (or RPM tranny). I have been looking at the LG Cams for a while and I love the sound of the big boy a member is selling in parts...however, after digging around a bit...it seems that a stock TQ on my A4 is not going to provide me or the cam the benefits a nice 3600 stall would...sooooo....I am back to looking for a cam with decent output, daily driver capable, and plays nice with my current stock TQ and A4. I guess I need to be in the 1500 to 6000 RPM range to get the best bang for the buck out of my stock setup...
-oh, and stay in my budget!
I am from the school where if you get into buying parts for an upgrade or mod, get the best you can whilst not breaking something downstream or causing further mods to be done just to handle the first mod...

I've got the bargain setup from Patriot in my car - expertly installed by Roger at Horsepower Sales Pompano and tuned by Mike Norris. I'm very happy with my results, here's a write up:

You can check it out at the next Corvette Challenge on Dec 3rd at Moroso if you are interested. It's got a good lope. If you want loud, I'll sell you my Borlas... I had to take them off it was so loud! I loved it but my neighbors were going to run me out of the neighborhood I'm afraid.
That G5X3 is a beast of a cam... but not so hot for torque it seems - look how high the peaks are, and check the torque down low around 2k where you drive on the street. Joe (dmtnt) has one in his track car, you can search for his posts and I think he posted a graph, compare to the graph in my post above. I wouldn't use that cam in an automatic, but some might say I'm getting old.
And don't make the same mistake I did, be sure and get the underdrive pulley. It's cheap 10 hp when you do a cam and it is certainly useful for bragging rights if you're into that!

Actually our torque is pretty similiar Joe....
You do have me by 10 ft-lbs until about 3,700 where my torque "perks" up and shoots to 360 then levels off and "perks" up again at 4,500 to 375 and peaks at 4,700-5,200 running 396.xx.
The power delivery on the G5X3(in my car anyways) has the EXACT same curve as factory ZO6 dyno pulls, just with of course more power throughout the range.
I do agree with Joe though on not putting this cam in an auto. If you do for daily driving you will need a large stall, probabaly in the 3,600 range and I personally don't like the feeling of a huge stall for around town daily driving.
I would probabaly with a high 220 to mid 230 range cam and higher 500's lift(G5X1, G5X2, F13 etc). That should put you in the 2,000 to 6,500 rev range and not require quite as big of a convertor.
Good luck with your cam choice, it's a difficult item to choose!
I would also splurge and get the UD pulley. If not, you'll be kicking your self later.

Hi GUys
We have numbers on M6 vettes with Cam only that reach 430rwhp and about 400 torque. This is with just a CAM ONLY with our LG herders and an air filter. Add AFR heads and you will be amazed.
Plus if you want easy hp with almost stock+ idle we have cams from our original G5 cam to G5X-1 through G5X-4 depending on your needs.
Feel free to call us and we can fix you up with any level of power and drivability that you are looking for.
We have cam packages that will work well with your Auto (A4) transmission with good drivability. We can tailor your package to exactly what you are looking for.
Give us a call.
Thanks
Lou Gigliotti LGM

Well those are on an LS6 with headers which is different than the question ie. LS1 without headers. 40 hp different?

Lou is right on with the numbers...
My ZO6 made 437.6whp and 396.1wtq.
My dyno curve is nearly identical to the top graph, only with less torque and more power....
Mods are Vararam with airbridge
LG's LT'S without cats
GHL Magnum Plus
G5X3 with Comp 921's
Spec 3 with alu. flywheel
NLP underdrive pulley
Oh did I metnion it was miserable out that day...rain, humidity etc. I was hoping for 425/400, and was pleasantly surprised!

I picked up 52rwhp with the G5X-3 cam. That was with a conservative tune though. I keep the timing low for my nitrous. But if I was to stay N/A I would imagine I could squeeze a few more ponies out of her. Go get the cam. Match it with some LG headers and some stingers, you will be in heaven. I did that same setup and everyone always says that it is the best sounding/meanest vette they have ever heard...

Without headers, I would not even put a cam in A Vette. I think the progression will be Cold air intake, Headers, then Cam.
BY definition, a CAM ONLY package assumes that the car already has air filter and headers. Cam only implies NO HEADS, rather than no headers. I am sure that you know this since you have over 2000 posts.
The Auto cars will still see about 400-412 rwhp. Our best A4 car was in the 414 range but that was an 03 LS1 car.
Hope that helps.
