Are all small block Chevy harmonic balancers the same?
You can use a balancer from any SBC except a 400, as long as the diameters are the same to clear your timing comb. Put your own TDC mark on if they’re not in the same spots.
How do I choose a harmonic balancer?
As a rule of thumb, the longer the stroke and greater the torque, the larger the diameter and mass. However, larger dampers can affect the acceleration and revving ability of an engine, so the right diameter and mass can help you strike the right balance.
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.
Can you use a 305 harmonic balancer on a 350?
The bore stroke on a 305 is different than on a 350, so the torsional vibrations modes (and the frequencies and rpms that they resonate at) will be different than on the 350 tahn on a 305, so the damper design is different for each engine.
Does size matter on a harmonic balancer?
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.
