I have never owned an 84. So what is the differences between the model years.

I know 84s only came with the duke.
Trunk lid and venting.
suspension, brakes?

I saw metromatt is selling his v8 84 converted to a fastback. Looks like a nice car. Has the firebird interior. Down sides to the car is no ac and it is an 84. But I don't know if being an 84 is really a downside. The suspension has been lowered, I think.

Your insights will be appreciated

Besides the cosmetic differences that you mentioned before, the 84 has a similar platform to the 85-87s. That is the structure of suspension, brakes, spindles,a- arms, and uprights are pretty similar. The biggest difference is the wiring harness and transmissions/engine choices. But if what you are looking at already has a v8 in it, someone has already taken care the biggest issue with an 84 engine swap. So this would not be an issue. If it has a nice firebird interior then you probably would not notice a difference in interior options either.


I say if it is clean you should go for it. Any of the upgrades that you could do for an 85-87 with a V8 you could do with an 84.

I dont think I have overlooked anything. (Then again I am a little 84 biased )


edit to add: the 2nd gen headlights are nicer on the 86-88 (i think) but they can also be used in earlier models with little modification.

The biggest visual difference is one you already pointed out. That is the decklid has a different style for venting air from the engine compartment. Other miniscule differences is that the front fenders are unique in how they bolt to the car, and thus if you have to replace an '84 panel and you try to use a different year you have to make minor modifications. Otherwise it is not much different from any other year.

If you are looking to purchase the car with the V8 swap you should not be discouraged due to what you may have heard about the '84 model. There is nothing particularly wrong with it in regards to other model years, and when you think about it at being around 134,000-ish or so Fieros sold for that year makes it the most produced year for Fieros.

I have owned an '84, and if given the chance I'd own another.

The cradles are slightly different. 85 cradle was made to accept the V6

87 came the gen2 headlights and gas expansion tank.

87-88 are the second gen headlight motors. Close but no cigar.
