More power
A larger camshaft can increase cylinder airflow and produce more power through the middle and upper engine-speed range.
CAM UPGRADE BENEFITS
What an LS Cam Upgrade Can Change
More torque
The correct cam can improve torque in the rpm range where you use the vehicle most.
Stronger throttle response
Cam selection and custom tuning can make the engine feel more responsive when accelerating.
Choice of idle sound
Select a calm street idle, a noticeable chop or a more aggressive lumpy note.
CHOOSING THE RIGHT CAM
The Biggest Cam Is Not Always the Best Cam
A camshaft should suit the complete vehicle rather than one desired dyno number.
We consider:
- Engine size and compression ratio
- Manual or automatic transmission
- Standard or upgraded torque converter
- Diff ratio and vehicle weight
- Intake and exhaust system
- Normal driving rpm
- Desired idle quality and exhaust note
- Naturally aspirated, supercharged or turbocharged use
A smaller cam can often provide better low-speed response and road manners. A larger cam may make more peak power but require a matched converter, exhaust and valve-train package.

INSTALLATION PROCESS
What Happens During an Oztrack Cam Upgrade?
Vehicle assessment
We review the engine, transmission, current modifications, fuel and the result you want.
Cam and parts selection
We match the camshaft with suitable valve springs, pushrods, timing components and supporting parts.
Disassembly and inspection
We inspect accessible components for wear or damage before final assembly.
Cleaning and installation
Cylinder heads and removed components can be cleaned in our hot wash before the new cam package is assembled.
Preload and valve-train checks
We check pushrod length, lifter preload, spring suitability and other valve-train requirements.
Pro-Hub dyno tuning
We custom tune the engine and, where applicable, the automatic transmission on our Mainline Pro-Hub dyno.

The exact parts depend on the engine, camshaft, existing components and intended use. Your quote should list the parts included in your package.
POWER AND TORQUE
How Much Power Does an LS Cam Add?
Results vary with engine type, cam size, exhaust, intake, compression, cylinder heads, fuel and transmission.
A correctly selected cam should improve more than the peak dyno figure. It should provide useful torque through the target rpm range and suit how you drive the car.
Oztrack measures and tunes cammed combinations on a Mainline Pro-Hub dyno. We check power delivery, air-fuel ratio, ignition timing, knock, idle control and drivability.
CAMMED AUTOMATIC VEHICLES
Do You Need a Higher-Stall Torque Converter?
Not every automatic cam package needs a large converter. Mild cams can work with a standard or modest converter when the cam is chosen for that purpose.
Very large cams usually make less torque at very low rp, have to idle faster and may need a higher-stall converter to move the operating range closer to where the cam works best.
A converter may be recommended when you want:
- A larger camshaft
- A more aggressive idle
- Stronger acceleration from a standing start
- Better low-speed manners with a large cam
- Improved performance at the drag strip
We consider your gearbox, diff ratio, tyre size, vehicle weight and normal road use before recommending a converter.
CAM AND HEAD PACKAGES
Can Cylinder Heads Be Upgraded at the Same Time?
Yes. Cylinder-head work may suit combinations targeting more airflow and higher power.
Replacement LS3 heads
We offer cnc ported heads with new ductile iron valve seats on an exchange basis. This is to prevent valve seat drop issues.
CNC-ported heads
Ported heads can increase airflow when matched to the engine, camshaft and intake combination.
Aftermarket heads
Premium aftermarket heads may suit larger naturally aspirated, stroker or boosted engine builds.

COMMON QUESTIONS
LS Cam Upgrade FAQs
How much power does an LS cam upgrade add?
The gain depends on the engine, camshaft, intake, exhaust, compression ratio, cylinder heads, fuel and tune. A cam normally provides its best result when matched with a free-flowing intake, exhaust and custom dyno tune.
Which camshaft is best for my LS engine?
The best cam depends on your engine size, transmission, converter, diff ratio, exhaust, vehicle weight, driving style and desired idle. Oztrack can recommend a profile after reviewing the complete combination.
Will an LS cam make my car hard to drive?
A correctly selected and tuned street cam should remain practical to drive. Very large cams can reduce low-rpm torque, vacuum and idle quality. They may need a higher-stall converter and more careful tuning.
Can I keep the standard torque converter?
Some mild camshafts work with a standard converter. Larger cams normally benefit from a matched higher-stall converter. Oztrack will advise whether your chosen cam suits the existing converter.
Do I need upgraded valve springs?
Most performance camshafts require dual valve springs matched to their lift, lobe profile and intended engine speed. Standard springs do not provide enough control or clearance.
Should pushrods be replaced during a cam upgrade?
Performance chromoly pushrods are normally recommended. Their length must suit the cylinder-head, gasket, lifter, rocker and camshaft combination so the lifters have the correct preload.
Should LS lifters be replaced during a cam upgrade?
Lifter replacement depends on the engine, mileage, lifter type, camshaft and condition of the existing parts. AFM and DOD engines normally require a complete delete package when fitting a conventional performance cam.
Can Oztrack delete AFM or DOD during the cam upgrade?
Yes. Oztrack offers cam packages for L76 and L77 engines that replace the AFM or DOD camshaft and lifters with suitable non-AFM components. The ECU calibration is also changed.
Will the engine need a custom tune after the cam is fitted?
Yes. A camshaft changes airflow, idle vacuum and cylinder filling. The engine calibration must be adjusted for idle airflow, fuel, ignition timing, throttle response and safe full-load operation.
Can Oztrack make an automatic car sound lumpy?
Yes. The camshaft and tune can be selected to produce a noticeable idle. Some automatic vehicles can be calibrated for a stronger idle note in Park or Neutral and a calmer idle in Drive.
Will a cam upgrade use more fuel?
Fuel use depends on the camshaft, tune and how the car is driven. Larger cams can use more fuel at idle and low speed. Some mild cams can retain reasonable cruise economy when correctly tuned. Our FE cam helps LS engines provide good fuel economy for a V8.
Can a cam upgrade be fitted to a supercharged LS engine?
Yes. A boosted engine needs a camshaft selected for the supercharger, boost level, exhaust, cylinder heads, compression ratio and intended rpm range. A naturally aspirated cam is not automatically the best choice for a boosted engine. We have a few great, proven supercharger cams.
How long does an LS cam upgrade take?
Timing depends on the vehicle, package, parts availability and whether inspection finds other work. Oztrack can provide an expected timeframe when quoting the specific job. Less than 5 days is common.
What information should I provide when requesting a quote?

- Vehicle model and year
