I suspect the best fix will be to install an adapter and use a Dodge 8 speed transmission. There is a kit to adapt a LS to the Dodge transmission, but you will need a modified driveshaft. It seems the "hot ticket" is a Chevy LS, backed up with a Dodge transmission, connected to a Ford differential. The bonehead prize would be a Ford ecoboom hooked up to a GM 10 speed transmission and a Dodge differential. Fortunately nobody makes any of the adapters to do this.
