Are cammed cars reliable?
Summary of the Article: Are Cammed Cars Reliable?
Camming refers to the modification of a car’s camshaft, which can improve performance within a specific RPM range. However, camming a car can have both pros and cons. One drawback is that cammed cars may be less fuel-efficient, especially at low RPMs. Additionally, these vehicles tend to have rough idle and may require careful tuning. Nevertheless, many people have successfully daily driven cammed cars without any issues.
Here are 15 questions and detailed answers about cammed cars:
1. Does camming a car make it less fuel efficient?
Any performance cam will lower your gas mileage. Economy driving does not typically require camshaft modification since it operates at low RPMs and low velocities.
2. What is the point of camming a car?
Camming allows you to build a custom engine that performs better within a specific RPM range.
3. Can you daily drive a cammed car?
Yes, you can daily drive a cammed car as long as all the hardware is in good condition and the tune is appropriate.
4. What are the cons of camming your car?
A common drawback of camming is inefficient performance at low RPMs due to changes in lift and timing.
5. Can a camshaft damage an engine?
Camshafts should last the lifespan of the engine, but failing camshafts can lead to extensive and expensive engine damage, requiring immediate replacement.
6. Can you over cam an engine?
Over-camming an engine can have negative effects on power and enjoyment. It is important to match lift, duration, and lobe separation angle correctly.
7. Are cammed vehicles illegal?
Most states allow recording audio and video in cars with dash cams, but some local laws may require passengers to be notified.
8. Do cammed cars idle rough?
Cammed cars may have rough idles and shudder at low RPMs due to exhaust gas leaks and dilution of the intake mixture.
9. How many miles will a cam last?
Camshaft seals are typically made to last around 80,000 miles but may wear out prematurely in certain cases.
10. How many miles does it take to break in a cam?
After initial engine operation, it is recommended to change the oil and filters after about 50 miles to remove metal particles from the break-in process.
11. Does a cam damage the engine?
A broken camshaft can cause significant damage to various engine parts, including the crankshaft, cylinder block and head, valves, pistons, and connecting rods.
Does camming a car make it less fuel efficient
Any performance cam will lower your gas mileage (period). If you are going for economy and not performance then there is no need to port the heads, since economy driving is done at low RPMs and velocities are low.
What is the point of camming a car
The term “camming” refers to the modification of a truck's camshaft. While it may sound justifiably complex, the process of changing out the camshaft allows you to build a custom engine that performs better within a particular RPM range.

Can you daily drive a cammed car
I daily drove a cammed manual transmission car for years–in traffic. I loved every second of it and would love to do it again. So long as all your hardware checks out and nothing is too aggressive, along with your tune, you should be able to daily it no problem.
What are the cons of camming your car
The most common con in camming your car is that it will be inefficient at low rpms. Due to the increase in lift and timing, the cylinders don't get sufficient air/fuel mixture to run it at low rpms.
Can a camshaft damage an engine
Camshafts should last the lifespan of the engine – at least 186,000 – 248,000 miles. Failing camshafts can lead to extensive and expensive engine damage which is why they need to be replaced immediately after failure symptoms have been identified.
Can you over cam an engine
"The very worst thing you can do is over-cam an engine," Consolo says. "Lift, duration, and lobe separation angle need to be matched to the true end purpose; getting any one of those wrong can over-cam the engine, which is worse than under-camming." That's from both a power and enjoyment perspective.
Are cammed vehicles illegal
Most states don't prohibit you to record audio and video in your car with a dash cam but some local laws require you to notify your passengers if they are being recorded. A simple verbal notification or a sign may suffice. Most U.S states have one-party or two-party consent laws.
Do cammed cars idle rough
And at low rpms with a modified cam, some exhaust gas leaks into the intake tract so the idle mixture is diluted and some intake mixture blows thru the exhaust. All this makes the engine 'lope' or shudder at low rpm. It soon clears up when accelerating.
How many miles will a cam last
The camshaft seal is made to last for around 80,000 miles but in some cases, it will wear out prematurely due to damage to the camshaft. The heat that the engine produces can lead to the seal becoming damaged over time.
How many miles does it take to break in a cam
First, put about 50 miles on the engine and then drain the oil and swap filters. This will get rid of the majority of the metal that ended up in the oil during break-in.
Does a cam damage engine
A broken camshaft can have a major impact throughout the top end of your engine, doing serious damage to parts like the crankshaft, cylinder block and head, valves, pistons, and connecting rods.
How many miles does a camshaft last
On average, the camshaft seal in your automobile should last around 80,000 miles.
Why do camshafts break so easily
The failure is usually attributed to one (or more) of the following: insufficient lubrication, improper break-in, reusing old/worn components, mechanical interferences, and inferior hardware/hardware not torqued to spec. Always use the camshaft moly paste that is included with your flat tappet camshaft set.
Is cam bad for the engine
A vehicle with a damaged camshaft may suffer from reduced engine performance due to cylinder misfire. Your vehicle may hesitate and lose power, jerk or shake aggressively, consume more fuel than usual, and produce more emissions.
What is the average price to cam a car
The average cost for a Camshaft Replacement is between $1,400 and $1,631. Labor costs are estimated between $885 and $1,116 while parts are priced between $516 and $516.
Is it necessary to break-in a cam
Breaking in an engine with a flat tappet camshaft is critical to its performance and long life. This mates the lifters to the cam lobes. Most camshafts will come with specific break-in procedures.
How many miles does it take to break-in a cam
First, put about 50 miles on the engine and then drain the oil and swap filters. This will get rid of the majority of the metal that ended up in the oil during break-in.
How much does it cost to cam a car
The average cost for a Camshaft Replacement is between $1,400 and $1,631. Labor costs are estimated between $885 and $1,116 while parts are priced between $516 and $516.
Are cammed cars illegal
Any modification is illegal (even just changing the mufflers) unless it's certified by CARB.
How much is labor for cam
The average cost for a Camshaft Replacement is between $1,400 and $1,631. Labor costs are estimated between $885 and $1,116 while parts are priced between $516 and $516.
How much HP does a comp cam add
LQ4 Cam vs Comp Cam
After installation of the Comp cam, the power output jumped to 550.3 hp and 512 lb-ft of torque. The cam swap improved the power output by more than 100 hp, but the gains were even greater out near 6,500 rpm.
Is every car cammed
Cam is short for camshaft, the engine part that opens and closes the valves to let the air-fuel mixture in and out of combustion chambers. Every engine manufactured today has, if not one, then at least two or more installed.
What does a Stage 2 cam do
Product Description. The LS1 Stage 2 camshaft was designed for enthusiast who want to increase power while maintaining excellent drivability and manners. This cams can be used with stock torque converters, stock rear gears, stock intake manifold, stock exhaust manifolds etc.
Does a Stage 3 cam add HP
It is a lot more aggressive and worth an additional 20 hp on top of the gains from the 8710 grind or 123 hp over a stock LS3 when combined with a stroker kit.
How much HP does a Stage 3 cam have
