Several thoughts come to mind after reading your post
1) The alphabet cams are getting kinda long in the tooth but some have
still been able to make power with them
I believe I've seen it said the "B" cam was made back in he old flat
tappet cam days and if that is so ... It would seem that it would be
mismatched somewhat on a latter model Stang with pcm control and
a long runner two piece intake and fuel injectors.
2) A Fox Stang behaves very differently after a h/c/i upgrade than a 94-95
as the pcm in each Stang is very different.
Having said that ..........
Your concern very well could be justified
3) I would focus my research around those peeps who have sucessfully
done what you seek to do with 94-95 Stangs for even more options and
ideas simply because ... more data is always better
4) I looked around in my files but couldn't find many combos using "B" cams
A few popped up so you can look for yourself.
btw ... I pulled those which were based upon iron head usage
