How to choose the right camshaft for your engine?
Choosing a particular type of camshaft for an engine build is an important decision that has to be made before any other parts are ordered or machined. Choosing a cam requires answering some basic questions, the most important of which is the engine application itself. Are you building an engine for everyday driving? For towing?
Can a bad camshaft sensor cause bad engine performance?
Bad Engine Performance – A faulty camshaft position sensor will cause an improper amount of fuel to be injected into the cylinder chamber. The engine will not respond very well to this because it depends on a proper mixture of air and fuel to function adequately.
What is the job of the camshaft in an internal combustion engine?
The internal combustion engine contains a device called the camshaft. The job of the camshaft is to manage the intake of gasoline and the emission of fumes from the exhaust system.
What makes a high lift camshaft more stable?
Consequently, you are more apt to round off a lobe on a high lift cam that has big lobes than one which uses smaller lobes with higher ratio rocker arms. The valvetrain also tends to be more stable when a higher percentage of the valve lift is generated by the rocker arms rather than the cam lobes, lifters and pushrods.
What kind of camshaft does a Chevy 4.3L have?
Edelbrock Rollin’ Thunder Camshaft # 3714 is designed for 4.3L 90 Degree V6 Chevy engines and produce optimum torque from the low-end to the mid-range. Rollin’ Thunder camshafts match with Performer manifolds for vehicles operating from off-idle to 5500 rpm.

How is the duration of a camshaft determined?
Cam Sizing Virtually every cam maker uses duration to rate camshafts. When someone talks about a “big” cam, they are referring to cams with longer duration. This keeps the valves open longer, increasing midrange and top-end power at the expense of low-end torque.
What makes a camshaft different from a Tighe Cam?
The camshaft does not have a larger exhaust, but a smaller inlet profile. This allows the camshaft to be solid as a 280º duration but has the characteristics of a 270º camshaft, because the inlet has more influence on the power band.
How does lift affect the size of a camshaft?
Lift and duration combined determine total open valve area—the space available for air and fuel to flow into and out of the combustion chamber. The more valve area open to flow, the more power an engine can theoretically make. The trick is to “size” a cam to optimize valvetrain events for your particular engine combination and vehicle.
Choosing a particular type of camshaft for an engine build is an important decision that has to be made before any other parts are ordered or machined. Choosing a cam requires answering some basic questions, the most important of which is the engine application itself. Are you building an engine for everyday driving? For towing?
When does a camshaft fail in an engine?
Typically a camshaft does not fail unless there is another serious issue with the engine – in which case the larger issue will need to be taken care of first. You may also be looking into changing a camshaft of you are wanting to increase the performance of your engine.
Do You need Timing marks for a camshaft?
The camshaft timing marks should be aligned correctly before proceeding. Tip: Some engines will not have timing marks. Those engines require the use of special tools that will hold the crankshaft and camshaft in place during servicing, and you may need to enlist the help of a certified mechanic.
Do you need a break in to install a camshaft?
Once you install your new camshaft, you may need to go through a break-in procedure, depending on what the manufacturer recommends. This can be quite an extensive job for some vehicles – and if you do it incorrectly, engine damage can occur.
