Are all small block Chevy harmonic balancers the same?
Small block Chevy harmonic balancers are not all the same. There are variations in size and design depending on factors such as engine type, performance level, and intended use.
According to the search results, here is some information about small block Chevy harmonic balancers:
– Chevy used different sizes of harmonic balancers depending on the engine and its performance level. The smaller 6.75-inch balancer (sometimes referred to as a 7-inch balancer) was commonly used on engines like the 283 and 327, while the larger 8-inch balancer was used on high-performance or Corvette motors.
– The balancers differ mainly in the position of the timing line scribed on the outside edge of the balancer. The TDC mark on the outside edge of the balancer will be almost exactly 45 degrees different from the keyway location on the inside of the hub.
– The larger balancer (8-inch) is designed to stabilize all the harmonics in the engine and is said to do better at controlling vibration and prolonging engine life.
– There are aftermarket options available, such as the Fluidampr, which features precision machined and computer balanced components.
In summary, small block Chevy harmonic balancers vary in size and design depending on the engine and its intended use. The smaller 6.75-inch balancer is commonly used, but there are also larger 8-inch balancers available for better vibration control. Aftermarket options like the Fluidampr are also available.

Does harmonic balancer size matter?
No matter what anybody tells you, size does matter when it comes to the harmonic balancer you use on an engine. Putting an incorrectly-sized balancer on an engine will do more than just cause it to not reach its full performance potential … it will cause serious damage to the rotating assembly.
What’s the difference between 305 and 350?
The difference in displacement comes from a different bore size. It depends on the use as to which is “better”. The 305 will do be better at fuel mileage due to its smaller displacement and drastically smaller ports and valves. The 350 will be better at power due to more displacement and larger ports and valves.
What size is a small block Chevy harmonic balancer?
JEGS Harmonic Balancer | Fits Small Block Chevy | 6.75” Diameter | Internal Balance | Exceeds OE Specifications.
Are harmonic balancers interchangeable?
All harmonic balancers ARE interchangable but you may need to get the right pulley for the power steering. Some had a rubber mount (old style. around the hub and newer ones were all iron and smaller but they DO interchange without affecting balance. Part II – NO, radiators are NOT interchangable.
Are 305 and 350 harmonic balancers the same?
It will fit The 305 and the 350 have the same crank in them. However if your balancer is the original 1985 It is a good idea to change it due to the flex mount getting old and slipping. Just make sure its the same thickness for pulley mounting.
What size harmonic balancer is on a Chevy 350?
Nearly all 350s came with an 8-inch balancer because of their relatively long stroke. An 8-inch balancer was used on the short-stroke, 3.0-inch-stroke, 302 Z/28 engines because those mills were intended for road racing.
How can you tell a 305 from a 350?
Here. You can see the difference in bore. Size. So the 305 is a significantly smaller bore it’s about a quarter of an inch smaller Chevrolet did have some other small blocks like the 307.
What size harmonic balancer for SBC 383?
If your crate engine requires a 400ci harmonic balancer – this is the balancer for you! Fits many popular 383 Stroker crate engine configurations from BluePrint Engines and many others.
Will a 350 balancer work on a 283?
The answer to both is yes. But make sure to either use the 59 timing cover or verify the timing mark is correct.
What’s the difference between a 350 Chevy and a 383 stroker?
A 383 is a 350 block bored 0.030″, with a 3.750″ crank (same stroke as a 400) instead of the 350’s 3.480″ stroke. It is a common combination, and if equipped with a good cam and heads, will make more horsepower and torque than a similarly built 350 (355 with the 0.030″ overbore).
