I'm soon to start working on my 1980 Z28 Camaro.
What i'm aiming for is a minimum of 6500 redline rpms but would love to attempt a hit at 8500
Good idea yes or no and how would i go about reaching it?

Piston materials, what should i use forged,hypereutectic or what?
I don't plan on using nos or turbo

Flat or domed pistons? (i've heard domed can lead to uneven distribution of fuel)

Cam and crank? Any prefered brands and/or materials?

lifters and rockers? Roller rockers of course but also i would assume what i use would affect the effective rpm range

it has a carb no computer etc so as for getting fuel in there quickly and effeciently i have no clue what to do here.

piston rods?

Also should i get a whole kit or purchase what i'm aiming for individually that would work together
I've done some surfing on the web to prepare myself and thus far it doesn't seem any engine rebuild kits come with a estimated rpm range

My reasoning is basically higher rpms mean more horsepower and when you shift gears the gear ratio changes and can effectively slow your acceleration down.
Also i'm unsure as to wether the max torque range would be increased if you have a higher rpm engine.

If i'm posting in the wrong forum sorry
Also right now i'm mostly looking at pistons and cams
Its got the stock 350 v8 in it from birth. I beleive the bore is 4 inches unsure about rod length etc or valve clearance. I've been told by my dad and still have no clue how he remembers all this to do with a car but my mind is like a seive dun na na dun na na...

first thing get rid of the 350 if you want more hp and rev strength. Look into a bigger block definitely. I'm running flat top speed pro pistons in RED and with my closed chambered heads, the bore etc I'm running 13 to 1 compression ratio... or so I've been told. Cam options are great, some love Isky cams, comp cams, I run a Lunati solid lift race cam and its been very faithful. You need to figure out how deep your wallet is first off. All hi performance motors will go as fast as your wallet will allow. You can do alot of old school tricks to pull out performance without NOS or superchargers. Daffy is great with the Chevy motors here he is a plethera of knowledge that one is. When building a race motor you have to consider all your options. What heads you want to run, for the money Dart heads or Camel backs have great compression ratio to help you motor down the track. You also want to look into roller combinations as less friction inside your motor will give you better horse power. Basically anything that will cause drag will steal your horsepower. For instance if you run a regular fan with belts etc.... to cool your ride you steal horsepower from the motor. If you run electric fans to cool the radiator you will improve your hp. I would look into a performance intake as well as headers, definitely take time to consider the carb you run as it will make or break you as well. Electronic ignition, high performance fuel pumps and high pressure oil pumps are a needful thing as well. You really have alot of options. And most importantly do you still want to run pump gas. You can build them to stout to run with pump grade fuels.

Well i'm a little skeptical about big blocks
This car is going to be something i take to the strip once in a while to have a little fun with and legally do a 1/4 mile
Other than that it'll be like an outing car
Something to go out with friends/dates/outings with.

I currently have 800$ saved up and am aiming for 4000$ to drop directly into the engine and another 1000$ for cosmetic things

It'll be a mostly responsibly used street car.
I don't plan on racing it other than the strip.

I'm 19
It's probably not practical but i'm sure it makes sense with the age included :P

I hadn't thought of the accessories as it relates to stealing horsepower from the engine, Definately going to look into things along those lines. As i said it will also be a road car but where i can afford to change parts out that will take less away from the engine I'll definately do that.

At this point in time i'm focusing on the engine so i don't get distracted. But your information was definately helpful.

I've also heard too large of a carb will kill your horsepower.
Yea pump gas will be run.
I'm trying to build something... amazing, able to be driven in city without too much consumption of gas (at least 10 mpg) and something i can enjoy for a while.
As far as nos and turbo/super chargers are concerned they probably won't be put on or in at first or ever. I haven't decided yet. I like the idea of a naturally aspirated car, i geuss i'm old fashioned?

My berreta however will be rebuilt in the distant future with a turbo and probably Nos.
