Actual width of hipo timing chain

  • Wanting to confirm with the community the actual width of the hipo timing chain. Tony Gregory’s book, incorrectly I believe, states it is 13/32” (0.406”) wide and the regular chain is 1/2” (0.500) wide, meaning OUTSIDE width.

    When I measure my NOS Ford hipo timing chain (C3OZ-6268-A) still in the box, it is .630” at the widest point, which is at the pins.

    When I measure an original regular early 289 chain, it is 0.720” wide at the pins.

    Can someone confirm these measurements are correct, and also there is no such thing as a 13/32” wide hipo chain? That number is actually the hipo gear tooth width, and thus the INNER measurement on the chain.
