Specialty Harmonic Balancer 1955 2004 Chevrolet Replacement Parts Review

Thanks to my knowledge gained in practice, I couldn't help but notice the superb quality of this harmonic balancer replacement part. The installation process was seamless and the result was a much smoother engine performance. The precision engineering and superior materials used make this a great investment for any performance car. The only downside was the slightly higher price, but the quality and durability of the part make it worth every penny.

The center hole was too small for my factory crankshaft pulley flange. I have a Big Block 454 Gen V. Gently widened the hole and everything turned out.

I installed it on a zz4 sbc 350 in my '88 Chevy truck, you need to pull out the center harmonic balancer bolt as well as 3 pulley bolts. The OT -Marking on the cover perfectly matches the original balance mark. It also has 90 degree marks for adjusting my roller rocker arms using the 90 degree method. No unwanted contact with the timing cover or the water pump is even close. Very good Detailing.The pointer does not cover the degree markings as some say.Get black markings easy to see.
