Scania,
Welcome aboard!
You've just found what is likely the best technical automotive site on the WWW, and certainly the best site for ThirdGen "F" cars.
Specifically, what information do you want? There are several chapters of facts and Technical Articles found at the home page of this site. Many of these contain very specific information about various topics related to our cars. Is there something specific you wanted to know? We'll be glad to help.
Generally, a 1988 Camaro IROC-Z should have either a 305TPI or 350TPI engine. The fuel system is a batch-fired digital fuel injection with a Bosch Mass Air Flow sensor, oxygen sensor, and individual port injectors to control fuel delivery. Fuel rail pressure is regulated and varied depending on engine load. The 1988 model also uses a Cold Start Injector to deliver extra starting fuel in cooler air temperatures.
Ignition timing is controlled by the powertrain Electronic Control Module (ECM) and Electronic Spark Timing (EST) module. The EST uses a detonation sensor to monitor combustion and adjust timing as necessary to provide maximum efficiency and prevent engine damage. Cooling fans are controlled by the ECM as well.
That is a very general description. Are there any specific questions?

Thank you very much vader. I would like to know a little about how much horsepower my engine have. My registration says 176 kw
something like 240 horsepower can that be
correct?

One point I should address. Some reference manuals refer to the 305 TPI as an "H.O." engine. In all respects, there is no such thing as a 305 TPI H.O. Yes, there were camshaft differences used, but GM makes no differentiation in the outer labeling of these engines..... a 305 TPI is a 305 TPI. The only "true" H.O. designated by GM is the L69.

Scania,
170kW, or 227 horsepower, is about the correct net power output for a stock 350 TPI engine. That power would be rated at the rear wheels. The crankshaft power output would be about 12-15% higher.
A good way to reduce some of this driveline loss is to use fully synthetic lubricants in the engine, transmission, and rear axle. SLP Automotive performed dynomometer tests on syntheic lubricants in a 350 rear wheel drive car. Their results showed a 10 HP increase at the rear wheels from the engine oil change alone, and another 6 HP gain from the rear axle oil change. Changing the automatic transmission to synthetic oil provided a small gain as well, but since the transmission oil must have some lower lubricity levels to allow the clutches and shell bands to engage without slippage, gains would naturally be small.

Thank you for all answers. So iguess my 305 has about 170kw. I installed new Flowtech headers with thermotech wrap and a 3 inch
exhaust system all the way from the engine.
So now my car runs like a dream.Its very fast.

Scania,
I may have misunderstood your original post. I presumed you had a 350 CID engine. Your last post indicates you have a 305 CID engine. That engine is rated at closer to 195 HP at the rear wheels, or 145 kW.
Verify the engine type you have. This should be indicated in the VIN, found on the dash panel plate. The eighth character of the number is the engine code. An "8" in that position indicates a 350 TPI, while an "F" indicates a 305 TPI.
I live in a 150-year old midwestern US/Swedish settlement. There are probably almost as many Volvos and Saabs around here as you might see on a daily basis. Yes, a ThirdGen "F" car can be very fun to drive in that kind of traffic.
