Harmonic Balancer
1964 convertible, 327-300HP. I need to replace the harmonic balancer on my rebuild. The one that came on the car (it's not the finned type) is 6 3/4" diameter and 2 3/8" from snout to face. Some vendors are saying this is not correct for my car.
Does anyone know what the correct size should be?
Anything over about 7 1/2" looks like it will hit the fan pulley so I'm confused as what I should have. I bought the car non running.
If I replaced it with a new one the same size, would it harm the motor or affect it in any way?
As always, thanks for the help.

I think the finned one was used in special high performance SBC. A base 300 is not. So yours could be original

Damper Docter and Damper Dudes may have some pictures on their websites. Also check out LICS (Long Island Corvette Supply) website…………..which will have pics of the correct one for your car.
