I had one years ago in a '67 Firebird. When the water pump failed I replaced it with a 350 chevy. I don't remember needing a different bellhousing when I swapped, but this was 1977 or 1978 and I don't recall all the details...

I think my solution to a failed water pump cost about twice what I had paid for the car.

1955 1st GMC Suburban | 1954 GMC 250 trailer puller project | 1954 GMC 250 Hydra-Matic | 1954 Chevy 3100 . 1947 Chevy COE | and more...
It's true. I really don't do anything but browse the Internet looking for trouble...
