V8 gasoline engine tranny(-BZ) has bigger bellhousing than diesel. Diesel bellhousing is better for conversion, diameter fits quite nicely together with whiteblock AW, M90 and 5-cyl M56 bellhousing.There is one in California on EBay for $799 USD

Funny how in Europe diesel is more common and as well more manual transmission cars. Makes building/modifying easier in this case.
