How Do You Use A Degree Wheel?
Is Degreeing a cam necessary? No, you do not need to degree your cam.
What is the point of Degreeing a camshaft? The purpose of checking or degreeing-in the camshaft in the engine block is to determine whether or not the camshaft is installed in the correct relationship or phasing with the crankshaft.
However, the most important step in phasing a camshaft is finding absolute T.

How do I know if my cam timing is off?
If the engine timing of the cam is off, your car will either be running rough or not at all. If the ignition timing is the problem, it isn’t as easy to notice because it has four cycles: Intake valve sucks in air while fuel is delivered by the injectors. The fuel mixture is reduced.
Can you degree a cam with the heads on?
Move or bump the degree wheel, and you have to re-establish TDC.
We didn’t include the price of a piston stop because for jobs where the heads are off the engine, you can make one out of a steel plate with a couple of holes drilled.
For degreeing with the heads on, you can make a piston stop out of an old spark plug.
How is Cam degree calculated?
How is it measured
What is a degree wheel used for?
Sometimes one side of the wheel is marked 0 to 360 degrees. This side is used to check duration of cams. When doing this rotate the crank until the lifter reaches your checking height.
Should I advance my cam timing?
Not to be confused with ignition timing advance, advancing a camshaft will change the timing of the valve events in relation to where the crankshaft is positioned. Changing either affects engine performance, but a camshaft that is properly installed in an advanced position can noticeably improve performance.
Can Cam Timing cause pinging?
This is why you run advance in your ignition timing, but again, it has nothing to do with cam timing.
With too much static compression and not enough octane in the fuel, you’ll end-up with pinging (detonation) problems and won’t be able to run enough timing to make any power.
How much can you advance a camshaft?
Advancing or retarding a camshaft’s timing from its original “zero” position causes the valve events to happen either earlier or later in the engine’s cycle. A camshaft that is advanced four degrees will cause each opening and closing event to occur four degrees of rotation sooner than before.
What are the symptoms of bad timing?
Symptoms of a Bad or Failing Timing Belt
You Hear A Ticking Noise Coming From The Engine.
Your Car’s Engine Won’t Turn Over.
You Notice An Oil Leak Near The Motor.
You Experience Exhaust Issues.
Your Revs Start Acting Up.
What happens if ignition timing is off?
If ignition timing is too far advanced, it will cause the fuel-and-air mixture to ignite too early in the combustion cycle.
This can cause the amount of heat generated by the combustion process to increase and lead to overheating of the engine.
What makes a choppy Cam?
Lope is cause by the intake charge being pushed back up the intake tract as a result of late intake valve closing.
How do I test my cam centerline?
Finding the Intake Lobe Centerline
Step 1: Roll the cam over until an intake lobe is up and pre-load the dial indicator so it will track on the lobe.
Step 3: Roll the cam backward until the gauge reads .
We got 72.
750, so we’ll call it 73.
Step 3: Roll the cam forward, past max lift to .
Step 4: We got 154.

Which valves are open at TDC?
Intake stroke. The piston is now at TDC, both the intake and exhaust valves are partially open. As the piston travels back down the cylinder, the exhaust valve goes fully shut and the intake valve goes fully open and starts to shut.
What is considered a long duration cam?
A 280-degree-duration cam holds the valves open longer than a 260-degree-duration cam.
Holding the valves open longer allows more air and fuel into the engine and also allows more to get out through the exhaust.
Longer duration (higher number) improves top-end power but almost always sacrifices low-end torque.
What do the cam numbers mean?
The first two numbers are the degrees of opening being 210 for the intake and 218 degrees for the exhaust given normally at .050 inch of lift. The next two numbers are the valve lift of intake and exhaust in thousands of an inch. The final number is the degrees of overlap.
How do you know how much overlap a cam has?
How is it measured
?
A flat-top piston allows the flame front to disperse evenly along the piston head, whereas putting a dome atop the piston interrupts even flame front travel.
So, all else being equal, the dome itself is almost guaranteed to cost you some power just because the mixture doesn’t burn as evenly or as quickly as it could.
