Beats me, not to argue, but I've rebuilt the 351-C in my 73 mustang two or three times, and each time I had to order the crank kit and specify auto or manual. I've got a '94 F250 sitting in my driveway with a 351-W, Manual trans and a rod knock. I've been told by every junkyard and reman' outfit I called that they didn't have a used engine or reman'd short block for a manual on hand... If the cranks don't matter, I may be able to fix it when I get some spare time.

Pic: Basic part number 6303: How many 351C cranks do you see for 1973/74?
I only see one (D2AZ-6303-A) and since the parts catalog doesn't specify the trans type, it's the SAME for A/T & M/T

If you look at the bottom of the page, you will see November 1988 on the left and Final Issue on the right.
This was the final edition of the 1973/79 Ford Passenger Car Parts Catalog and by this time (11/88) the D2AZ-6303-A crankshaft was no longer available from Ford.

All the car/truck parts catalogs I have after 1989 are on microfiche, so I can't post pics from them.
1928/89 Ford car/truck parts catalogs are available on C/D's, so I can post pics from these.

The only Ford crank that I remember being A/T specific was the ol' D2AZ6303B 400 CID car crank. Before the 400 was 1st put in to trucks in 1977 there had never been a "regular production" 400 with a M/T behind it. And no Regular Production Car with a 400 ever had a M/T behind it. So the D2AZ6303B wasn't machined for a pilot bearing. Later on D2AZ6303B was replaced by D7TZ6303A. The Pickup and Bronco crank. Which would fit in front of M/T or A/T.
