1985 cutlass engine swap
 

I have a 1985 cutlass supreme v6 3.8L I'm new to this my first ever swap I am currently looking at getting a 383 stroker small block. Will this engine fit? Is this the right engine for my cutlass? Whut type transmission will I need? Are motor mountsI have good? will I need new ones? Whut about drive shaft? Is there a lot of modifications with this engineI will have to do? Is there any engines 383 or 350 will be fine that's a direct fit with hardly any to no modifications.? Any feedback will be appreciated.
THANK U.
