Will be putting my 73 bird together hopefully this summer. Originally came with a 400 but the project came with a running 440. Going to install the 440 so I can get it running while I rebuild a 400 that I recently got. Will be running HP exhaust and original pipes. So question of the day, is the 440 exhaust system the same as the 400.
