motor swap from 3.4 to 5.7

i have a question fellas i have a 1995 firebird 3.4 v6 and i have a 350 with .025 popups and a 450 lift cam what all would consist of a motor swap i know the fuel injection but what will work i can't find the intake manifold along with a computer and harness. but what else pertains to an engine swap in these cars i am used to old school vehicles. what do yall think?

Suspension, engine harness, computer, crossmember, motor mounts, radiator, alternator, steering?, possibly transmission. Its alot of work.

Cheaper and easier to sell your car and by a LT1/LS1 powered F-Body.
