Gentlemen I understand the 3.4 was used in many different vehicles. If you had just a motor is there a way to identify which model of car it was originally for. Am I correct in assuming they had different setups for various models ie horsepower ratings etc. Reason I ask is I have found one for sale but the owner has no idea what model of vehicle it came from, as he acquired it as part of a package deal or something. I asked for the engine no ( A95092BAS ) but can find nothing relating to this. Would hate to purchase this and then find out it could be from a something other than the Camaro/Firebird and be less horsepower/slower ?

The 3.4 Camaro/Firebird was 93-95 only. It had iron heads. Same heads as the Fiero. It should have an "F" casting on the side of the block.

I will ask them to check, which side is it stamped on ?

I don't know which side, but it's reasonably large and is a raised casting. The seller may be calling a 3400 a 3.4. If it has aluminum heads it isn't a Camaro/Bird 3.4.

Edit: I found a picture but can't post from my phone. The F is cast into the block just above where the Fiero started is located. Below the #6 exhaust port if the heads are on the engine.

Does the engine still have the intake on it? If it's a F-Body 3.4, the intake manifold should look like a big letter Y. If the intake looks like a spider, then it's a 3400. See photos below.

Also, I forgot to mention that the F-Body 3.4 actually has less horsepower than the 3400 V6. And as far as I know, there was no "less horsepower" version of the iron-head 3.4 V6. So if you accidentally got a 3400 V6, you're actually getting "bonus" horsepower. You'll also be getting a roller cam, reinforced engine block (stronger than the F-Body 3.4 block), and a reinforced bottom end. You also won't need to drill holes for the starter mounting bolts, because they're on the correct side. The downside is that if you want to use the Fiero heads and intake, you'll need to swap in 3.4 V6 pistons, because the iron heads on the 3400 engine would have really high compression with the stock 3400 pistons.

Didn't know it was on both sides. The picture I found only showed the other side of the engine. It would be difficult to see that side on an automatjc equipped car.

Definitely your first pic Blacktree, but what I wondered was if that engine was used for anything other than the Camaro/Firebird and if so was it altered/detuned ?
