Engine choices FE or 427 Windsor

[1985 CCX]

I have a friend looking to install a motor in a SPF.
The choices range from Shelby FE with injection to a Roush 427 SB.
He feels injection is a keeper. He is thinking Weber stack type injection.
Choices……..
…………….Shelby FE
or
…………….…..Roush 427 stroker
or
Recommendations………

What do you think as I only know 60’s iron. He wants new not old….
He is after light weight reliability with power of old.
Thoughts and why appreciated.

Also, transmission of choice.

Does shelby sell complete engines or just blocks
