Problem with the new Big Block Chevy Mid-Mount Complete Accessory System
I recently purchased this system (Part # 20-242) for my new 502HO crate engine. While I was mocking everything up I notice that the diameter of the crank pulley (Part # 97-318) locating boss was .010” smaller than the inner diameter of the locating hole in the harmonic balancer. Normally these diameters are exactly the same to ensure the pulley is perfectly centered on the balancer. This prevents it from wobbling and causing destructive harmonics. Even though the pulley is held in place with three bolts, there is still too much play. Is there anything that can be done to fix this?
