There are several write ups about all the info youll need to perform the swap. A non roller block can be converted to accept a roller cam though Im pretty sure youll need to run a reduced base circle cam. Another option is to use linked roller lifters though theyre expensive. Your accesories will bolt right up. Search Pokageek, he did a 408 swap which is just a stroked 351. Youll find his thread useful as he ran into and solved a lot of little problems that most people dont anticipate when doing a swap like this.

to use a hydraulic roller cam in a non-HR block, you need link bar lifters. they cost about $500. using a small base circle cam is not recommended
 
Swapping a 351w into a Fox is virtually the same as doing it in a 94-95 Mustang.

The only things I can think of that may be different...

The sn95 is said to have a little less hood clearance
The sn95 ecu MIGHT have a little more trouble adjusting to the increased displacement than the Fox ecu.


Ford never put a 351w in a Fox, but they did put one in an sn95...

I have info on my site, listed in my sig...

good luck,
