What are the specifications on a cam card?
Most manufacturers will list the exact specifications for each cam on the cam card. The length of time the valve is held off the valve seat from the cam lobe. This is measured in degrees of crankshaft rotation. Duration at .050-inch Lift
How does the camshaft synchronize with the crankshaft?
This is a process that synchronizes the camshaft with the crankshaft. For best engine performance, builders use a degree wheel to dial in this measurement. Most manufacturers will list the exact specifications for each cam on the cam card. The length of time the valve is held off the valve seat from the cam lobe.
What does it mean to degree the camshaft?
Degreeing the Camshaft This is a process that synchronizes the camshaft with the crankshaft. For best engine performance, builders use a degree wheel to dial in this measurement. Most manufacturers will list the exact specifications for each cam on the cam card.
How is the lift of a camshaft measured?
The length of time the valve is held off the valve seat from the cam lobe. This is measured in degrees of crankshaft rotation. Duration at .050-inch Lift This is the distance measured in degrees of crankshaft rotation from when the valve is open at .050-inches until it’s .050-inches from closing.

What is the serial number on a comp Cam?
The 7661-11 is a serial number specific to that camshaft only. We compared these specs to the catalog and because there is no list number on the end of the cam, we will assume this was a custom-ground camshaft. COMP offers this as a service to anyone who is looking for a custom combination of specs that are not listed as an “on-the-shelf” cam.
How does the summit racing cam timing calculator work?
It converts duration, lobe separation, and advance into the four individual timing events that will ultimately dictate engine performance. It also works the opposite way. You can tweak any of the four events in the calculator to learn what the resulting duration, lobe separation, and advance would be under the new conditions.
Where can I find the comp CAM Master Catalog?
Under that heading toward the bottom we found a tab for the Cam Lobe Master Catalog. This is the COMP Cams equivalent of the Rosetta stone for cam lobes. In the catalog, you will see the cams listed by configuration starting with flat tappet hydraulics and then hydraulic rollers–which is what we want.
Where can I buy a JEGS camshaft kit?
Consider the intake system being used, cylinder heads and a host of other factors, and you’ve got a real dilemma. JEGS carries a warehouse full of camshafts and cam and lifter kits from mild to wild in lift and duration.
Can you beat the L79 Cam at every rpm?
With that said I still wouldn’t go near that L79 cam or the plus version. Even an old aftermarket design (within reason) should be able to beat it at nearly every rpm point. However if you’re just looking for that sound then go for it. But it will sound a little milder in a 350 because of a little more CI’s.
What is the power range of a camshaft?
Operating range 1000-3200 rpm. Operating range 1500-4000 rpm. Good low end and mid range. Operating range 2000-4800 rpm. Operating range 2200-5400 rpm. Good mid range power.
