Today, we will enlighten your thought by describing what size cam is in a stock Chevy 350. It is such an engine that is as familiar as the heart of the car.
Here, you will find it to work for rotating and creating a continuous delivery of energy. This rotational energy pushes the springs. In this way, the valves get opened, and fuel can access the cylinder. The size cam in a stock Chevy is a crucial part of the engine to keep it running.
What Size Cam Is In A Stock Chevy 350?
The stock Chevy 350 cam is a .518-inch (12.1mm) diameter, 127 duration at .050 inch (1.27mm) tappet lift. The bore is 3.485 inches (88.6mm).
The stock Chevy 350 has got introduced in 1971. Here, you will find that Chrysler Motors was a renowned motor vehicle manufacturing company. They have made this in that particular year. You know what; the heavy-guarded and powerful 350 engine is a crucial organ of enormous trucks and cars. It gets more modernized over the decades in the USA.
We will get to know the entire specs of this stock size cam. Besides, the workability of the size cam will come, and functional features will display the utility. The time has come to know about what size cam is in a stock Chevy 350. Let’s have a move to the next steps.
It is our prime objective to know what size cam is in a stock Chevy 350. Here, the two-piston of Chevy 350 contains a bore of 6 inches. Along with the bore, it has got a supplanting of 350 cubic inches.
The size specifications are the broader sense of calculation. Similarly, we get to assume the overall capacity of the engine as well. The ring piston is an integral part of working smoothly. Next, we must get a quick view of it.
The compression ratio made a cumulative pressure on the piston. In this way, it gets shifted to the open side and closing sides. The actual measurement of the compression is 3.8 inches. Along whit this compression, you must measure the different grinds as well.
We usually find that it has 12 to 24 grinds in a sum. Next, the connecting rod of the engine is 5.6 inches in length and 3.44 inches in width. It can stroke the engine heavily.

Main Features of Cam in Stock Chevy 350
Piston Firing and Valve Timing
The Chevy 350 stock size cam has a fantastic piston, containing the proper firing order. Plus, its first piston commences fires following through the respective orders. You will see that the last firing order will be the second piston.
Here, the set of ordering is the significant portion of the piston. Its workability keeps the engine runs smoothly. Thus, the middle piston, which is seventh, can boost the power efficiently.
We must take the valve into action. You know what; the valve usually commences at 18 BTC and ends at 52 ABC. You will also find that the exhaust valve has got more heightening power. Somewhat, its functionality seems to be the reverse mood of the first one.
The exhaust valve commences at 56 BTC and ends at 16 ABC. Here, these valves have contained a module of 32-degree overlap. Both the valves have got 24 seconds each in a sum.
In the Chevy 350 timing chain, you will find that it has contained 70 links in total. The timing chain has an asphalt of 0.345 inches. Besides, it acquires a width of 0.624 inches. We have seen that the Chevy 350 contains a hydraulic and oversized cam.
Along with this, you will also know that it has hydraulic lifters. The centerline of the lobe will work accurately. Here, it is quite crucial to know its specification as well to understand the functionality.
The lobeline has a rocket arm with a rotating ratio of 1:6, which increases the engines’ smooth and fastest run.
Besides, we may shift our focus to the hydraulic lifter, which can perform high due to this rocketing arm. It also has the functionality to make the exhausting valve opened and ended. In this way, the timing chain works efficiently.
Now, it is time to know about the torque specification of the Chevy 350. The bolts have a connecting module to the timing chine. For this reason, you will see that there are three bolts. These things typically generate 22 pounds of torque efficiently.
Here, the first bolt made a connection with the rod. It has got shifting power to move the pistons to the crankshaft. The evaluation torque of this process is 34 pounds. Respectively, we have found that the second bolt creates 42 pounds, and the third one generates 70 pounds.
If you have a stoker transmission in the form of the carburetor, you will find optimal compression. Besides, it is a particular module to prevent the expected losses. We usually find that it has a set of cam and lifters, which enrich the engine’s compression power.
Besides, it works in a two-way shifting module. Here, the loss of the compression is a vital part to lessen. Every engine loses a little or more compression while running. For this reason, there should be a module to systemize the loss to lead to a lower level.
The Chevy 350 has got a thumper cam to lift to the highest peak of the compression. Here, it works fast and prevents compression loss efficiently. The thumper cam hits the two valves and closes the air vent quickly.
Moreover, the exposure of the exhausting valve is small. It decreases the losses. Besides, we may look for the quick-moving of the cams. It depends on the smooth functioning of the engine. Likewise, you need to focus on the operating range of the machine.
The size cam can perform well for this matter. In other words, we must be animate of the engine’s RPM level to produce the highest power.
We hope you know now what size cam is in a stock Chevy 350. You will get no alternative of size cam to boost the power of your engine. With a machine-like Chevy 350, the users should have the best size cam. The enriched functionality matters most in the case of performance and utility.
