Will a turbo 400 transmission previously attached to 454 big block engine attach 350 small engine?
Yes, a Turbo 400 transmission that was previously attached to a 454 big block engine *can* be attached to a 350 small block engine. However, it requires the correct bellhousing. The bellhousing used for a big block is different than the one used for a small block. You'll need a small block Chevrolet bellhousing for the Turbo 400 to mate correctly to the 350.
