Notable considerations go with valve lift & actual duration at standard lift. Neither valve lift nor actual duration remains the same on different models. However, you can consider higher numbers for a more powerful outcome.
Of course, we’re talking Chevy 350 small block engines. But the versions are likely to differ, requiring your attention to the manual. Don’t forget to look into the supporting specs on the exterior. It should help with a hassle-free installation.
As it happens, it’s not impossible to find all the options to fit your Chevy. But the overall response from the engine will differ, no matter what. And you want the optimized power on the output. So, consult pros or experts to narrow the preference.
Simple highway boosting requirement is not the same as racing conditions. Cams are pretty good for street or strip applications. Therefore, you’ll have to specify the intention of using the power. It’ll also help to shorten the available options.
The arrived package is likely to contain camshaft & lifters only. Upon availability, the contents are likely to include some essential items. Check the details to ensure the included accessories before confirming your purchase.
How to Remove & Install a Camshaft in a Chevy 350?
Introducing a replacement requires prior removal of existing automotive parts. And the process appears somewhat difficult with complex steps. Despite your high knowledge of engine parts, you better leave the job to a professional.
It all starts with the proper removal of your existing camshaft. The primary steps seem to continue as follows.
#1. Start looking into the manual to check the camshaft specs. Park the vehicle on a reasonably larger level surface.
#2. Open the front engine hood, let the internal system cool. Use wheel chocks to stabilize the vehicle’s rear wheels.
#3. Carefully place the jack stands to jack your vehicle’s front side. Put the stand right under its welded body pinch.
#4. Locate all the assembled parts from user manual diagrams. Utilize a belt tensioner to remove the belt drive.
#5. Confirm whether you actually need to remove the engine. For removal, loosen the connectivity from other parts.
#6. Locate the timing cover on its structure to get complete access. Gently remove the cover using suitable gear.
#7. Lower the oil pan level by clearing the crankshaft snout. Disconnect the battery terminal before loosening the bolts.
#8. For ignition coil connectivity, disconnect all the wires. You’ll require a dependable ratchet & socket for the process.
#9. Remove the exterior valve cover to find the internal parts. It explicitly concerns the lifter set, locker & pushrods.
#10. Eventual metal wear is likely to get the valve cover stuck. Gently use a pry bar with the proper force to break the joint.
#11. Start removing all the connections in the intended order. Keep the parts securely placed in a suitable space.
#12. Try to maintain a straight order in accessing the engine. Don’t forget to clean individual tools using a clean cloth.

#6. Try to maintain an exact alignment of the assembled parts. Spend a good time restoring the cover connectivity.
#7. Use your hands to tighten the holding bolts. Ensure intact tightening with a suitable tool, avoiding over-tightness.
#8. Complete the installation to close the engine hood. Make sure to have the proper engine assembly alignment.
#9. Lower the vehicle to the ground, removing the jack stand. Start the engine to conduct test drives for detecting its response.
Frequently Asked Questions (FAQs)
Question: How Does a Camshaft Work?
Answer: Camshaft controls fuel input to the combustion chamber & exhaust fume expulsion. And the functional part of any cam is its lobes. The spinning of the camshaft forces the lobe to open & close the valves with the moving piston.
When the piston inside the TDC (Top Dead Center) moves downward, the intake valve gets opened. The valve immediately closes, flowing the piston to the bottom out. At the same time, the exhaust valve gets opened at the BDC (Bottom Dead Center). It occurs at the end of the combustion stroke to complete the exhaust stroke.
Increase in RPM (Revolutions Per Minute) triggers an interdependent increase in opening & closing. In fact, the number is almost half of the imposed RPM. To support the combustion, the air-fuel mixture starts to enter the cylinder fast.
Question: How big of a cam can I put in a stock 350 Vortec?
Answer: There are many associated factors to decide the cam size specs for stock 350 Vortec. But the most important consideration lies with valve springs. Also, you need to focus on the actual duration of the standard lift against the maximum valve lift.
Starting with the actual duration, anything close to 220 at 0.050” should suffice. But the limit on actual duration counts pretty wide for the intended Vortec. You can consider a safe limit of 0.525” or 0.500” valve lift with a standard 1.5 rocker.
Question: What is an “over-cammed” car?
Answer: Before getting to an over-cammed issue, you ought to know the meaning of cammed engine. It primarily refers to the throatier sound with power enhancement flowing as a replacement. Installing a new cam notably improves power through altered duration, valve lift & timing.
And the mechanism explicitly concerns the overlap of exhaust & intake duration. The operation must continue at a suitable compression to generate the demand.
However, excessive overlapping of the intended duration calls for over-cammed engine issues. It occurs when you fail or improperly settle the compression to match the overlap. Your engine starts to induce too much noise with minimal boost, particularly at a lower RPM range.
Question: How to fix an over-cammed car?
Answer: As you should understand, the problem explicitly lies with the compression ratio. You’ll have to reset the compression ratio to skip the over-camming issue. Of course, low RPM consideration may give you initial trouble with proper settlement or consistency.
Different cams require variable compression ratio to hold the overlapped action. Exact compression ratio should immediately fix the problem to generate the output. For the discussed stock 350 Chevy, the preferred ratio is likely to remain at 9:1, 9.5:1, or even 10:1.
Question: How much HP can a stock Chevy 350 handle?
Answer: From the mechanism, you have to catch the interdependency of associated factors. High operating RPM range imposed further torque to produce power. And the standard measurement of increased power comes in horsepower (HP).
There’s no viable limit on the possible increment of HP on stock 350 Chevy. You may consider a thumb rule – larger block experiences lower HP in comparison to small block engines. Any standard Chevy can deliver a maximum of 350 to 375 HP.
And big block Chevy engines can get 400 up to 475 HP. Unfortunately, no exact rate concerns the small blocks. Upgrading some interconnected components can provide 500+ HP. But you better keep the power under 400HP to avoid safety threats.
Question: How will a camshaft improve my car?
Answer: Aftermarket camshaft in brand-new condition promises to improve the car power. The already explained mechanism in the earlier section should keep things clear. Apart from the output, your engine starts to function smoothly.
Overlapped duration initiates additional torque to generate the power. Likewise, the operating RPM range plays a major part in deciding the output. It immediately enables extra horsepower to initiate a dependable boost.
Also, the throttle response gets better to hold your acceleration at a convenient rate. Any high-quality camshaft requires no extra amount of fuel to produce the outcome. Therefore, your fuel consumption remains the same.
Question: The car is not running properly with the new camshafts, what’s the problem?
Answer: It’s possible to encounter issues following the installation of new camshafts. As it happens, different facts are likely to prevent the camshaft from functioning. You need to conduct a thorough check to detect the exact culprit.
Improper installation, mechanical interference, incorrect valve spring pressure, excessive-end play – anything can trigger the issue. Even the cam itself may appear broken, defective, or faulty. For its complicated mechanism, you better consult an expert or professional for the job.
Question: Does a Camshaft Make a Car Louder?
Answer: Increased RPM support enables faster opening & closing of valves. And it’ll surely generate noticeable sound from the engine. In simple words, extra sound comes with additional power on the output.
And the limit remains acceptable, even at higher horsepower. However, nothing outrageous shouldn’t take place in this regard. Too loud noise from the engine means probable distortion in functionality.
You can’t expect a faulty, defective, or failing camshaft to produce the energy. Only the best cam for stock 350 Chevy can hold your engine up to the mark. And you’re sure to make the decision from our aforementioned options.
Without a doubt, Lunati 10120102LK Bare Bones seems the most preferable choice for Chevrolet. Its balanced design enables a consistent boost for power through ample torque. Settling down the drawbacks, you can obviously afford its initial tag.
