Ok i ve done some search but i would need some member input.Im about(monday/tuesday) to put a cam in c5z.I ll try to give every single info on my car so i could get the best answer

I already got brand new in the box ready for the install:

-Precision Race Components Double Valve Springs Rated To .675" Lift
-Precision-Machined Titanium Retainers
-Hardened Machined Spring Seats
-New Viton Valve Seals
-Tsp chromoly hardened pushrod
-Harlan sharp rocker 1.7
-Complete ls2 timing chain/sprocket set
-Fast 36 lbs injectors
-2 water pump gasket and 1 timing cover gasket
-ARP Crank bolt

My car already got on it:

-1 7/8 inch ARH Long tube
-3 inch to 2.5 ARH catless x/pipe on stock TI
-Vararam vrb2 with powerduct intake
-TC1 10% UD pulley(i change mine last year because it was seperating)
-EE 3/8 tunnel plate
-Dte trans brace
-Some misc stuff(b&m sport shifter,TPE oil pressure relocation)

The main fact about the car:

-Made 390whp/373 wtq with bolt on only / stock cam
-Stock head (243 casting) with stock intake(will be doing head and intake in a couple of years)
-Was going toward a blower nut change my mind because i dont wanna worry about heat and i really like cammed car
-The car will be a 95% street car driven hard(week end warrior only) and will see 1 or 2 event of auto-x / road circuit
-Will keep my 3.42 because i like longer gear
-Would like to have the best power / drivability

Right now i was set on a G5X3 Cam (236/242, .600/.610 on 114lsa).But saw the Tsp torquer V3 (231/234 .643"/.598" 111 LSA) wich got a higher lift but lower duration...They got both in stock at the shop...

I already know that the LG will give me around 440/450whp but will not gain a lot of torque down low wich i probably dont care since i dont wanna spin the wheel all the time on hard launch.I also know that the stock rod bolt dont like to be spin higher than 6800rpm so i always shift around 6600/6700.

From the info that i gave you, wich one would be the best for me ??? Feel free to give your personnal input.Im open to learn something everyday

Thanks in advance
Eric

 

On my bolt on Z with LG Pro's the Torquer V3 was good for right at 50rwhp gain on the dyno. Keep in mind a 111LSA is not for everyone.

 

My buddy had been admiring my Modded Z for the last year. He said he loved the way mine sounded and how my car always pulled away from his 2002 Z06. His was pretty much Stock. Except for Cold air intake, Black wing and Exhaust. He took his Car to the Performance shop, got LG headers installed, G5X3 cam, springs, pushrods, and Dyno Tune and all the other needed item to complete the install. When we went to pick up his car. His first reaction was "Sounds Awesome" then he got in it to drive it. He didn't understand why he now needed to give the car mild GAS along with releasing the clutch to get it going. He kept saying "Before I could just let the clutch out and the car would go" I said you wanted a CAM didn't you! "Ohh the Car Shakes now!" You wanted a CAM didn't you!

So after he drove it for two weeks he spent the money to stick the stock LS6 Cam back in it and get it re-tuned.
He never had any intention of taking it to the Track, he just liked the Sound and wanted more HP.
I tired to explain torque curve..etc to him, but he said he knew what he wanted. I tried to let him drive my Car to so he could feel/see what a properly Cammed/Tunned car drove like, but he refused. I have a 230/236 .592/.602 114LSA. I told him I thought the G5X3 is pretty big for a Street Car, but he didn't listen. $3500 lesson learned. Just telling you my Story. And yes I agree A cammed Car is not for everyone and a 111LSA.. MOLY

 

Any dyno graph to see the power/torque curve ?

My buddy got a 02 camaro ss with ls6.He got what i would call a copy of the g5x3(ms3 on 112) so i know what it looks like to drive a cammed car.And i know that i want a cam

Thank you both for your input.

Keep it coming.

 

Sorry, I guess this just caught my eye. My buddy didn't understand the compromise between large Cams and friendly street driving. He never grasped the concept of his car now making the power in the higher Rpms rather then lower like before. I just remember him stalling a couple times and saying how his car felt slower from a stop light. Not saying your like my friend, just thought I'd share the story incase someone did not know what they were in for. BTW. I love my Cammed Z! But then again, I'm not my buddy or a Doctor.

 

Your comment where more than welcome.I ask the question to have different input from the most member that i can to be sure to choose the best cam between the 2 .

 

I've seen the TV 3 consistently dyno 420-430 on a LS6. I had an off the shelf cam and will get a custom grind this time.

 

for a daily sort of car, i think you would prefer the torquer. both cars will sound 'cammed' so dont worry about that. the lower duration and tighter lsa will keep the car pulling at lower rpms where you will be at most of the time. i have recently been researching the same questions and am going for a torquey cam rather than one for max power.

i will caution you that due to the aggressive lobes you will have to start changing (or at least checking) valvesprings at intervals.

 

I ve read that i should changed the springs every 30 000miles to be safe...Is it the good intervals.

Im kinda surpised that no one seems to like the LG.But thats ok.I truly like this forum because there is always some good explanation with every choice instead of plain answer wich is very good to learn.

Keep it coming

 

By the way i edited my first post because i was probably not clear enough on the street thing,sorry about that.I dont know if this change anything...

It is not gonna be a daily driver.Yes it will be a street car but only a week end warrior.It will see some 3-4 hours trip but either of those cam will do it...i think.I do plan on head and intake after the cam but it will only be in a couple of years since im buying a home in the next 12 month.

Thanks

 

you would benefit from a rear gear swap with a large cam...will cancel out the low rpm torque problem associated with the larger cams

 

30,000 or 3,000 miles?

My car is a dedicated Track Day DE car. small cam with only a .581 lift. and sees 3000 to 6600 rpms ALL THE TIME. I use Comp 918s and change my springs each winter or about 2500 2800 miles


30,000 miles may not a good idea.

 

I've had the G5X3 cam in a Z06 and can tell you that you don't really want this cam in a street driven car as the idle is sometimes erratic and your idle speed will be around 1K.

You would much better off with a milder cam and maybe some head porting to achieve the same results.

I know that you don't plan to drive the car everyday but from my personal experience you would be better off with someting less radical.

 

Thank you all.I ll study your input and see what i ll do.Car is at the shop right now.
