you can reuse the fiero upper/mid/lower intake, or switch to the full camaro setup. (and have to convert to DIS)
the heads on the fiero/camaro are the same, get the shortblock, clean it up, new bearings, rings, etc, and you should be good to go, unless it has a bent rod or cracked piston or something.... if your feeling brave, new pistons

btw, the camaro intake flows alot nicer if you want to go DIS....
edit: dont forgot you will need to re-drill for the starter, and if you have a manual trans, you will need a neutral balanced (88 fiero) flywheel.
