Yes
No the 1988 underwent a big upgrade
There is someone with a Olds 455 in his Fiero, but he had to remove the trunk.
If you mean 1988 and they are both notchies, yes they will.

The engine support cradle is usually what fails
The 2.8 V-6 engine was first used in the Fiero in the 1985 GT. It was called a 2.8H.O. engine and had 140 HP. It was the same in 1986. However, the same engine was used in other GM cars but had 130HP. In 1988 Fiero horsepower was reduced to 135. how ever they say 140 HP but dyno tests proove that the 86 fiero gt has 200 HP
yep, did it. fiero engine/transaxle in tube frame buggy
It depends on what Fiero SE you own. There are two types. The earlier SE models, '84-'86, used a 85 mph speedometer for the four cylinder engine. It would not be until the '87 V6 model that the SE cars received the 120 mph "GT", as it's called, speedometer assembly. If you already have a 120 mph speedometer in your Fiero SE, it will work just fine. If it's the 85 mph speedometer, it will not, and would read incorrectly until you perform the necessary modifications to make it act like a 120 mph speedometer should.
