When A 350 Small Block Chevy Is Balanced, Is The Harmonic Balancer Balanced As Part Of The Rotating Assembly

Posted in Internal Engine Parts | Asked on May 25, 2010

Can you just replace a balanced engine’s (350 sbc) harmonic balancer with a fluid dampner without disassmbling the engine for re-balancing?

    I believe that the 400ci small block is the only one externally balanced. Make sure that your 350 crank snout is straight and true. Make sure your flex plate is spun balanced like a tire. Make sure you have a high grade timing chain assembly. Make sure your tranny torque-converter is spun balanced and has tight bearings. Torrington bearings can round-out quickly with hard launches throwing a vibration into the floorboards at mid to upper rpm reaches. (stock torrington specs).

    Yes you can just replace the balancer. Internally balanced rotating assemblies don’t absorb the harmonics they just reduce the amount of harmonics that are put out.
