The harmonic balancer has a single groove pulley riveted to it. It may well be from a 1957 Corvette motor. I'm guessing the harmonic balancer is not drilled or tapped for pulley(s). What are my options to upgrade to a double groove assembly?
PS The crankshaft is drilled and tapped for an bolt.
Thanks

Then you can install a double groove pulley. When looking for pulleys make sure you get the pulleys that correspond with the water pump you are using. They use a short shaft and long shaft on small blocks. | | | | | Joined: Feb 2006 Posts: 150 Shop Shark | | Shop Shark Joined: Feb 2006 Posts: 150 | Don, Thanks so much for the information. I have spent all morning searching online Corvette parts places and the local parts places seeking education and finally hitting pay dirt. I'm getting one dropped shipped early next week.
My education has verified that the motor is sporting a 57 Corvette harmonic balancer & pulley, but has a later model crank.
