I don't think there was a 351W in any 75 Mustangs. 74-78 were the Mustang II's.
In my experience most 73 Mustangs used the 351C, at least that's what I had in my 73 Mach I.
Be sure of what you are buying before you commit.
Yes you will probably need a new oil pan.
Most of the older Mustangs used a front sump pan which will not work with the 83 GT.
