350 lifter install
This may seem like a no-brainer, but this is something that is easy to miss when shopping for a camshaft. First, you should know the exact specifications of the Chevy that you own so that you know what camshafts will work for the engine and transmission that you have.
Knowing the exact measurements is a good idea as well, just in case, so that you can make an informed decision about which camshaft you think will fit the best for your Chevy model. The large range of products on the market means that there is a large range of prices as well.
This could make things more difficult to choose because you may be limited to a low-end budget. You just need to look at options that offer you the basics. Simpler options may have slightly lower RPM operating ranges but can still offer you high-performance and torque.
So, staying within your budget and getting something that works for you is possible. Like all of the options on this list, the level of performance that is offered by the camshaft that you purchase is a major factor to look at.
Depending on how much power and torque you are looking for, you can get what you want by looking at the performance and power that each camshaft has to offer. If you are looking for a small boost of performance , then a lower range option that is cheaper will give you what you need without having to opt for a premium product with a much higher price tag. But, if you are wanting to boost your torque and performance by a lot , then you will likely want to go with a heavy-duty option that will give you a high RPM operating range and lots of torque.
Those who want racing capabilities will likely be in the higher range, but you will be happy with the performance that you get, and be willing to pay a premium price to get it. If the lobe separation angle was at 0 degrees , both the intake and exhaust valves would be opened and closed at the same time.
So, the lobe separation controls the time that both the intake and exhaust valves are open, which allows the engine to work. So, this is something that you should look into when deciding what type of camshafts you want for you Chevy model.
With all this new information about camshafts , you have a lot to take with you. However, you may still have some questions about camshafts that you want to be answered before you lay down some cash for the best option. Well, you are not alone. Many customers often look up more information online before wanting to make a final purchase.
So, we have compiled a list of some of the most commonly asked questions and found answers so that you can get all the information you need in one place. This helps to increase performance and power for the vehicle and why camshafts are so popular. A camshaft is comprised of two distinct parts, the cams, and the shaft.
As the camshaft rotates , the cams or lobes move up and down. As it continues, the valve spring pushes the valve back up to close it. This creates energy that is used to produce more power in the engine that allows it to have a higher performance level. It can also allow for better acceleration timing and faster speeds. In racing vehicles, this is especially important because of the leg-up that it gives its drivers in a race that could end with a split-second win.
Essentially, the answer is yes. This is because the combustion chamber is open for a longer time per cycle which allows more sound to escape and makes a more booming sound. It is commonly said that, for each degree change in duration, the powerband of the engine moves up or down in the rpm range by rpm. This is true whether you are increasing or decreasing the duration. Whether you go with our top pick for its great features and high-performance , or you opt for going online and finding a different model to fit your needs, you now have the knowledge to make an informed decision about which product to choose.
With all the information given in this article, you can now be able to find and purchase the camshaft that fits your needs and works great with your Chevy, without having to spend time online checking reviews and specifications. So, save yourself time and money and pick one the great options on this list for your Chevy today.

COMP Cams CL Although all of the choices on this list make great options for you, there is one camshaft that seems to stand out from all the rest. High-performance stock converter 2, — 5, RPM operating range Comes with the camshaft, set of lifters, and assembly lubricant Early intake valve opening Long exhaust duration. This ranges from 2,, all the way to 5, RPMs to give you the largest range of top-notch performance. This ranges from 2,, all the way to 6, RPMs to give you the largest range of top-notch performance.
Some camshafts offer a good boost of performance and a mid-range operating range that will give you good overall performance at different RPMs, but others will focus solely on high-performance and give you a very high operating range that allows you to get the best performance within a large range of speeds.
Cam lobe separation is the degree of the angle between the maximum lift of a pair of cam lobes. Cam lobe separation is an important performance characteristic because it times the intake and exhaust valves. The pushrod will be seated in the lifter but not depressing the cylinder plunger of the lifter. There is a spring in the lifter that keeps the cylinder at the top, if you shake the lifter before installing you can hear the cylinder rattle as it depresses the spring.
When you seat but not depress the cylinder in the lifter you are at zero lash, It is the same if the motor was running and you loosen the nut till it clatters and then tighten till it is quiet. You can now install the rocker covers valve covers. There is no need to adjust them after the motor is running. It is much cleaner no oil sprayed everywhere. The lifters will rattle for about 30 seconds till they fill on the initial fire. This is the way I was taught when I went to Automotive school.
Hope this helps. My father and I used to build race motors and would run for a couple of hours with a big electric motor before the initial fire up with gas and electrics! My local engineering shop uses a milky colored assembly paste spread with a paint brush.
I believe this assembly lube is a part number. Check your workshop manuel. I once worked for a fully sponsored professional racing team, all the race engines were put together with assembly lube on all the parts. Than before start up we would spin the dry sump oil pump external belt driven until we saw oil coming out around the cam shaft the highest point on the engine.
You can do something similar by grounding your coil wire and cranking the engine until the oil pressure gauge comes up off the peg. I always do this on first start of any engine. I have never done a dry start on an engine with hydraulic lifters, but it seems to me with assembly lube on everything, and than cranking the engine until you get oil pressure, all of the lifters should be pressured up good enough for the first start.
Petros , Jul 23, I assume your cam manufacturer has mentioned which engine oil to use assuming we are talking flat tappet lifters, modern oils do not work with old cams.
Most that build engines will have an old distributor, which has it's shaft altered to fit a drill. This is used to spin up the oil pump, before cold start up on a fresh build. Most of the initial wear on the bearings, seals and other pieces will be during this start, until pressure builds.
This may seem insignificant, being only a second or two, but you can get a lot of damage and wear in this time. I always soak the lifters, so they don't have to "pump up" in the first few seconds of start up. PAR , Jul 23, You must log in or sign up to reply here. Show Ignored Content. Similar Threads.
