From what I've read there is more clearance with the Mustang style mounts between the pan and rack when using a 351W block.

Although using a non stock pan could throw that out the window. When I had my Mark VII (it used fox Mustang style mounts) the engine sat a bit higher off the K member than my Thunderbird.
