How much power?
Just bought a 73 204z. The car is not running right now but I plan on doing all the minor work and have the pros do the performance. My question is, how much power can I get out of the original OHC motor? I'm hoping to get about 230 - 280 hp. Is that possible? or Am I dreaming?

Good thing you have $$$... 280hp will cost about $10k. Rebello makes some killer L series motors: http://www.rebelloracing.com/eng_info.htm
Or for $5k you could have a 300hp+ built turbo motor... half the cost... more power... but who'd wanna do that?!

Not looking to go out like that, just want the car to pull when I get on the gas. I kinda figured 230hp was far fetched when the original only pushes 150 at best and that was 1973. Do you have any ideas to what I can do to get the most out of this motor?

So when you say you have money... maybe you should specify how much you are willing to spend.
Then we can see what mods are an option for you.

You can keep the orig motor... but to get 280hp, you'll spend close to $10k... and having an "original motor" that isn't original anymore kinda defeats the purpose of having an "original motor."
-3.0L/3.1L Stroker = $2000 (unless you are lucky & find an LD28 crank)
-Head machine work = $1000
-Block machine work = $1000
-Tripple carbs = $1000
-Motor hardware = $1000
-Exhaust = $500
-Other needed accessories = $1000 - $3000
-3.0L/3.1L Stroker = $2000 (unless you are lucky & find an LD28 crank)

the l24 is a good motor but dont look for those numbers out of it. get your hands on a l28 and its going to take a hot build to get close to those numbers
nismo pretty much gave u the run down. i guess if u have the money prove us wrong and get a 280hp out of a l24. go over to hybridz.org and do alot of reading. you will get confused and anxious. we can try to help you out as much as we can.

Right, Right!!!! LOL. What I should have said is original-looking. You know, putting V8 motors in the Z just takes all the originality out of the car in my opinion. The shell is a Z but the insides are totally different. Anyway, what can I do to get the most hps out of this motor?

If you can do headwork and such yourself, you will be in business. My buddy built a l31 stroker engine for his race car s130, and he did all the big work his self. He dynoed it at 347hp @ 7700rpm at the wheels!. This car will blow your mind. Ive ridden in it. I watched him race it, and he got the car to 160 mph on the 1 mile straight (on a track I forget the name of), and he was babying it! All in all, he spent no more than $3000 dollars on the engine, I can guarantee that. Its fuel injected btw.

best bet, make usre the engine is sound, full exhaust better carbs perhaps and a cam lightened flywheel and up the compression on the motor. usually you can achieve that by simply shaving the head down (at a machine shop of coarse)

Found a L28 engine
Ok peeps, I found a complete L28 engine with 5 speed transmission. Clutch was replaced 6 months ago, has new fan clutch. 98,000 mi on engine. After reading all the comments and advice the only thing missing from this motor is it not a turbo.
