How can I tell what camshaft I have?
Locate the ID number on the camshaft. It is typically located in the center of the cam between the lobes. The ID number will consist of either eight or nine digits; the last four numbers identify the cam and its specific application. Match the number to a Chevrolet camshaft part number listing.
How do you identify an unknown camshaft?
How to Identify a Camshaft by Number
- Find the model prefix. The model prefix is the first part of the camshaft number, and it describes the vehicle that the camshaft is meant for.
- Find the profile or grind number. This number should be on your camshaft, followed by a number of degrees.
How do you match a cam to head flow numbers?
For comparison of improvements, take the larger exhaust flow from one head, subtract the smaller exhaust flow from the other, and then divide that by the smaller exhaust flow figure. I’ve found this to be a very good method of comparing cylinder heads and choosing the proper camshaft to go along with it.
Do camshafts make a difference?
NUMBER AND LOCATION OF CAMS It doesn’t hugely affect performance, but different engines have different positions for cams, as well as different amounts of them. The vast majority of modern engines have four valves per cylinder, and these generally have separate cams for the inlet and exhaust valves.
How can you tell the difference between an intake and exhaust camshaft?
The intake camshaft opens and closes the intake valve (s) which let the fiel/air mixture into the combustion chamber/cylinder. After mixture is compressed and ignited, the exhaust camshaft opens the exhaust valve to let out burnt mixture/exhaust.
What do the numbers on camshafts 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.
What are the different types of camshafts?
Two major types of camshafts exist: flat tappet and roller. Within those categories are two options: solid or hydraulic—four variations in all. Tappets ride against the camshaft lobes—their movements open and close the valves.
How do I choose the right cylinder head?
When it comes down to choosing or comparing cylinder heads, the best way is to bolt them on and make some dyno pulls. The one that makes the most peak power may not always be the best choice if the rpm range is very narrow. You may want a head that delivers a broader range of power and torque.
How much horsepower do camshafts add?
You can expect up to 50-100 more HP with a good camshaft replacement. However, if horsepower is what you’re after, just changing the camshaft won’t be enough. You might have to change some of the other parts as well and get a few upgrades in order to really unleash the full potential of your horsepower.
How much does it cost to fix camshaft timing?
Camshaft Position Sensor Replacement Cost – RepairPal Estimate. The average cost for camshaft position sensor replacement is between $179 and $223. Labor costs are estimated between $72 and $91 while parts are priced between $107 and $132.
What is the exhaust camshaft?
The exhaust camshaft assumes a control function for the decompression of the cylinder. At a low rotational speed of the engine, the exhaust camshaft briefly lifts the exhaust valve during each stroke, so that the compressed air can exit and the engine starts easier.
Which is the best camshaft for a Ford?
Comp Cams has made it simple to pick the right cam with their XFI series camshafts and serious power gains are made so easy with nitrous kits from Zex.
What are the different types of camshafts and lifters?
Within the COMP Cams® camshaft family, there are several different types of camshafts available for most popular domestic engines ranging from the Xtreme Energy Cams™ to Nitrous HP™ Cams. In addition, there are various lifter types available ranging from Hydraulic Roller to Solid Flat Tappet.
What kind of camshafts does Crane Cams make?

What kind of camshaft does a Ford Stroker use?
With these two things in mind, Comp Cams designed a camshaft specifically for small block Ford stroker applications. Comps XFI Stroker Cam series includes two camshafts.
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?
Which is the best camshaft for a small block Ford engine?
A kit provides a no brainer solution that ensures you’ll have components that work well together. There seems to be a greater variety of roller-tappet camshafts available out there that allow you to dial in ford performance engines. The nice thing about roller cams is the aggressiveness they offer without sacrificing idle quality and drivability.
How long does a Ford racing camshaft take?
The duration figures in the shaded area are taken at 0.050″ tappet lift. This is useful to check the cam with a degree wheel during installation. The solid color is advertised duration. For comparison purposes, add intake and exhaust lobe centers and divide by 2 to calculate “camshaft lobe separation” specification for Ford Racing camshafts.
With these two things in mind, Comp Cams designed a camshaft specifically for small block Ford stroker applications. Comps XFI Stroker Cam series includes two camshafts.
