Most of the 32' Campbells built came equipped with v-drives. One of the boats called Electric Blue was actually retrofitted with a special high-speed hull and arneson surface drives, and it supposedly goes over 60mph, not bad for a 14,000 lb boat. My dad was partners for a time in the first 32', called Numero Uno, which was originally setup with twin big block chevys coupled together freight train style like a V16 with a single v-drive.
Campbell also built a bigger boat called Lady In Cement for Dan (Hoss) Blocker that measured 42' and had twin v-drives.
