I'm in the middle of rebuilding my 67 396 and the harmonic balancer has been beaten beyond use. What will interchange with the 396 balancer? Thanks

Any big block internal balance balancer, do not use a 454 they are xternally balanced not sure bout the 427 but for sure 402 or 396 will work Good Luck L89SEDAN

Harvey,
The 396, 402, or 427 balancers will all work. They are still available from your local Chevy dealer at a reasonable price.
