Hi, I'm very new to the Corvette and not even in your country!! I don't have a Corvette but what I do have is a Corvette engine in my old Australian Vehicle.
I know it's out of a C4 Corvette but what I don't know is it possible to identify what year range within the C4 run and does this effect buying parts?
Also I have found people saying good and bad things about the C4? and this has just left me a little more confused! what are the good and Bad points to the engine? have attached a photo that I hope will help.

Any help would be great.
Have you any way to verify that engine is truly out of a C4?
If it turns out to not have come from a C4 there is two possibilities that I'm aware of. That it came out of a Camaro/Firebird. One possibility is that it's a 305 TPI, and the other is that it's an L98 350 TPI like you get out of a C4 with some slight detuning.

All I have is the word of the former owner, what I do know is that it is a TPI 350 and the research that I have done the parts see to match the C4 engine with some non essentials (air conditioning etc) removed.
Is there someone on the engine that could help me with the identification?

Serpentine belt or v belts? V Belts would certainly be a clue that it's a 305 and not a 350 at least an early to mid 305 TPI anyway.
You could try the casting #s on the block and the heads. Those are pretty much a dead give away.
I was able to verify one of my spare engines did indeed come out of a 1985 corvette with those, after doing a search on google.
85-86 with cast iron heads had the valve cover bolts on the outside lip of the cover.....these are center bolts. So a later model ....or like mentioned earlier....Firebird/Camaro.

IF it is an L98 out of a C4 the installer did a lot of changes. (belts accessories)
There was a nineties chevy truck motor with stamped steel VC's like yours.
Iron heads and intake will accept the TPI system.

Judging by the valve covers (centerbolt steel) and the locations of the accessories on the accessory drive, my guess would be a Tuned Port motor from a '85 to '89 IROC or Z28 Camaro. The presence of a mass airflow sensor means not speed density so unless it was converted (highly unlikely), it is not a '90 to '92 motor.
The runners are also a giveaway that this was likely not originally a Corvette motor. I've owned three IROC convertibles over the years and noticed that Tuned Port Runners on IROCs and Z28s are a little different from the thicker and rougher finished versions used on the Corvettes. As other have mentioned, early Corvettes (85 to late 86) did not have aluminum heads.
Likely a 5.7, but it could also be a 5.0.

Exactly. Its a truck block and heads that will fit up to the early TPI without mods.
Remember guys, ALL center bolt Corvette heads are aluminum.
As is the intake manifold.
I have to agree with this. Its a rebuild or replacement 350 with a TPI intake. All L98 Vette engines were Gen 1 SBC so for all intent and purposes, you have a Corvette engine.
What engine do i have
