Thanks for the heads-up. What vehicles came stock with the E4OD?
I've got another idea, which might be simpler than a transmission swap. The suggestion about using the B-W OD as a divorced unit reminded me that I've got the remains of a Volvo 4-speed transmission that was married to a Laccock OD unit. The OD is gone, but there's a few of them on Epay worth the money, and a bunch less than a Gear Vendors unit. The Laycock was used behind the Austin-Healey I6, the Jag, and a few other torquey engines, and it's got its own built-in hydraulic pump. All it takes to make it work is an electrical hookup. I can use the Volvo output shaft to build an input for the Laycock unit and mount it on a crossmember behind the C-6. It would take a little fabrication work, but nothing that a lathe and a welder can't handle!
