"Ch**y used "football" shaped washers on their I-6s. They reportedly work perfectly on the Offy/EFI conversion on the Ford 300"
Yeah but then all my Ch**y buddies would never let me up. I can hear them now: "So you couldn't get that FURD to run without some Chebby parts on it huh?", or "Built FURD tough with Chebby stuff ?". Those GM boys can be brutal, you know!
I better just continue looking for some bigger washers, but thanks for the suggestion.
