Rebuilt BOP Th400 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

*FormerMember* · 05-06-2008, 04:37 PM

For guys considering a Cadillac or other non-chevy GM motor (Buick, Pontiac, Olds or Caddy). This does use the bigger, beefier Caddy internals. Trans is originally from a Caddy Coupe Deville with a 472.

Had this rebuilt and a NP203 output shaft installed. Includes a new torque converter.

500 plus the ride. I have about 600 into it. Going with a 4L80E... installed it into my C to K conversion and realized I wanted more gear in the differential for hauling heavy loads. NOTE that this has never been run, since the rebuild. I'll provide the phone number of my rebuilder for information purposes.
