I looked up all those engines for the firebirds on autozone, and none of the use a 41 inch belt. But i looked up a stock fiero 2.8 and that did use a 41 inch belt!
So now I need to get pictures up, becuse my engine from the side does not really look like the fiero's. And where it says 'Fiero' on the intake manifold, that is not there.

After you fix this engine, you can learn to re-size images.

I resized them half of what they use to be, but I still wanted them big so someone could get a good look at them and hopefully tell me what engine I have.

The 2.8 Fiero intake manifold from '85 and '86 just had a decal on it. Your decal was probably removed prior to the upper manifold being painted.

Are there any markings on the 2.8 or 3.1 or 3.4 that can determine what it is?
I know it has a holley throttle body.
I know theres some numbers and like a barcode on the alternator if that would help.
It doesn;t have a stock air filter.
I can't think of anything else to determine what kind it is...

Remind me again why we're trying to figure out the exact engine displacement?

Seems to me all you need to do (at least to get started) is to replace the fan belt and fill the cooling system using the proper procedure.

Well I already did replace the main belt and filled the coolant all up. And the engine is running great now. But I'd just like to know what kind of engine I have. The previous owner told me he swapped in a 2.5 6 cylinder from a firebird, but they never made those. So I'm just curious as to exactly what kind of engine I have. Especially if I have to buy parts soon

The guy probably meant 2.8 from a firebird. But for all intents and purposes regarding purchasing parts or maintenance for your car, just telling the parts store you have a Fiero with the V6 should get you the correct part. Everything I can see in your pics are Fiero parts. If the guy did swap in a firebird engine he probably just used the short block so the rest of everything else is Fiero.

Looks like it has the 85-86 Fiero upper intake manifold and Fiero valve covers (except for that chrome breater, and REALLY nasty looking intake tube). All V6 Fieros had those Holley throttlebodies. The alternator looks like the standard 85-87 Fiero V6 alternator. It has a nice shiny new MSD coil! The decklid support strut looks poorly mounted.

First thing I'd do is find the proper air filter and tube assembly to make sure the air is being filtered properly into the 'new' engine. Then repaint the hideous intake and valve covers and replace the spark plug wires (WAY too close to the exhaust manifold), then replace that horrible breather with a proper oil fill cap. The valve cover appears to be leaking at one of the bolts in one pic too.

Count the number of ribs on the water pump, alternator, and crankshaft pullies. I don't know if the Firebird engine had 6 rib pullies or no, where the Fieros had 5 ribs.

You need to take a picture of the belt side of the engine = the passenger side looking at the side of the motor. The pictures you have taken now don't really show much because they're directly from the top and those are all basic Fiero components.

The valve covers and intake have been painted... VERY poorly. That intake is terrible. Is there even a filter on it? It looks like they shoved the air flow sensor into whatever the heck that tube is and routed it directly into the stock location quarter area. Everything else looks to be legit Fiero stuff on the top side (Fiero alt and bracket, coil, etc.).

I do have to say I don't like that color on the intake and rocker arm covers.

I do need to repaint the intake because it does look bad, its all flaking off and scratched. But its not high on my list because I don;t have the money and there are other problems.
What do you mean by the spark plug wires are really close to the exhaust manifolds? Do I need shorter wires? There is an air filter on the end of that tube, just poorly done.
One question, when you turn your car on, and its idling or you are driving slow, can you hear the air being sucked into the filter? Because I can hear it pretty loud

There is a filter on it. The previous owner cut a square in the metal sort of by the wheel well and shoved the filter in there.
I will try to get pictures of that side soon.

There are 5 ribs on each of the pulleys, and the belt was 41 in.
I actually like that chrome oil fill cap though.
And it is leaking on one of the bolts, i tried to tighten it down but it wouldn;t go and farther and I didn;t want to break it. The guy that changed my oil said it is also leaking on the left side of the oil pan.
My alternator is different than the fieros because mine does not have that fan thing on it.

Yeah the air sucking thing is normal. Even more so with your intake.

How much does a can of spray paint cost these days?

Probably more than I have haha. I'd probably have to get some special high temp stuff too

No, not high temp.

I think the spark plug thing is just from the angle of the camera. I don't think they are actually that close.

It's probably a stock 6. Look at the seventh digit, after 37 (for coupe) of your VIN - is it a 9? A 9 means it was, and probably is, a V6. If it was originally a 2.5 liter four there would be an R instead of a 9. People say all sorts of things when they're trying to sell a car.

My VIN said it was a 2.5 4cyl. and that's how it is registered on the title as well

Wouldn't it be nice if people kept a record of major changes like new engines and other mods so later owners could figure out what to do? I bought a car in CA and drove it home to OH. The guy told me had run the AC without antifreeze in the radiator, causing the heater core to freeze, but he neglected to mention he had bypassed the plugged fuel filter with a copper line with a valve which I turned off because it was dripping over the alternator. It took till Springfield MO to figure this out and install working filters.

I thought about that with my 80 Mustang that I sold. '73 351C 2v, a 460 stock electronic distributor not sure what year, a 302 bellhousing, flywheel, motor mounts and a T5 tranny.

The 460 distributor plugged right into the origional 2.3l duraspark ignition and worked great.

I think Firebirds did have 3.1's in the 1989-1992 era. They also had 2.8's (before) and 3.4's (later). So you could have any of them.

glad to hear you got things worked out though.
