boss 302 engine swap?

my friend just bought a 68 coupe with a in-line six, and was wondering if he could drop a boss 302 in it, and if so would he have to change the motor mounts, and what other things might he have to do to it?

I own a Boss 302, don't bother. Just build a nice 302 with a good intake and heads.

Yes, motor mounts will need to be changed:)
