There is a guy over on the Caddy Forum that has a 472 in a 53, believe he is using stock frame, but a nice fit.

The old cast iron Saginaw transmissions were classified as a light/medium duty transmission (depending on the model). I've seen to many break behind small blocks to ever consider putting one behind a 454 or Caddy engine. I agree with Jerry about a 5 speed but do some reading on them first, even the World Class T5s were only rated for something like 300-350 Ft Lbs of torque (and you're looking at 500 Ft Lbs with either of the engines you're contemplating).


Jerry's thinking of the mounting for the AC compressor in the top center of the intake.......but it probably wouldn't take to much to remount the Alternator there if desired/needed.

By the way, welcome.
