Hi all. 1978 Magnum. Installed the 400 in place of the 318. 727 as well. Thought I could use the original Torque shaft assy. Maybe I was tied and rushing, but wanted to test fit headers and wanted to see if I need to modify things. Is there a differences from a 904 to a 727? FSM shows same number for all (3575 384) Didn't take photos of it. Any advise would be great.
