1987 MCSS engine swap

I am interested in swapping out the 305 (1987 MCSS) for a 1993+ lt1.
I have a few questions -

1. Can i use the stock motor mounts.
2. Can i use the auto tranny the lt1 comes with or can the stock one handle the new power
4. The LT1 is feul injected so what modification would i have to do to convert the rest of the car to feul injection (like change the lines?)

Or instead of the LT1, 350 crate engine that would be about as powerful for cheaper?

I appreciate any help
