ChatGPT response to the age old question.

QUESTION:

How to make a high horse power Oldsmobile 307 V8

ChatGPT ANSWER:

Building a high horsepower Oldsmobile 307 V8 engine involves several key steps and considerations. Here’s a general guide on how to approach this:

Engine Internals Upgrades:

Cylinder Heads:
Upgrade to aftermarket aluminum heads for better flow and performance. Oldsmobile W30 heads are a popular choice.

Camshaft:
Install a high-performance camshaft to increase lift and duration, tailored to your desired power band.

Pistons and Rods:
Consider forged internals for increased strength and durability under higher power levels.
Intake and Exhaust:

Intake Manifold:
Swap the stock manifold for a high-rise dual-plane or single-plane intake manifold for improved airflow.

Carburetor or Fuel Injection: Depending on your preference, upgrade to a larger carburetor or switch to electronic fuel injection for better fuel delivery.

Ignition System:
Upgrade to a high-energy ignition system with performance coils, ignition box, and spark plugs to ensure efficient combustion.

Exhaust System:
Install headers with larger diameter exhaust pipes and free-flowing mufflers to reduce back pressure and increase horsepower.

Cooling System:
Ensure the cooling system is upgraded to handle increased heat output. This may involve upgrading the radiator, water pump, and possibly adding an oil cooler.

Fuel System:
Upgrade fuel lines and pump to support increased fuel demands. Consider higher-flow injectors or carburetor jets.

Engine Tuning and Calibration:
Use a professional tuner to optimize fuel and ignition timing for maximum power without sacrificing reliability.

Drivetrain Considerations:
Ensure the transmission, driveshaft, and rear differential can handle increased power levels without failure.

Dyno Tuning and Testing:
Once modifications are complete, dyno testing is crucial to fine-tune the engine for optimal performance and reliability.

Maintenance and Upkeep:
Regular maintenance is essential to keep the high-performance engine running smoothly and reliably over time.

Keep in mind that building a high horsepower engine involves a balance of performance upgrades and ensuring all components work together harmoniously.

Research and planning are crucial to achieving your desired power goals while maintaining reliability.
 
I remember when you read a book by Doug Roe, David Vizard, or a Peterson Publishing rag and hung out with gear heads and got the same answers ......

The intelligence is artificial. But the stupid is real.

When the answer is this---

"Drivetrain Considerations:
Ensure the transmission, driveshaft, and rear differential can handle increased power levels without failure."

The next question I would have is this...
"So, in detail, how can I ensure the transmission, driveshaft, and rear differential can handle increased power levels without failure?"

I bet you get the same regurgitation of bland pablum that A.I. is famous for right now.

Of course, you may want to rethink things if you got this answer from an ED-209...

"You should know better than to try and build a powerful 307. Step away from your electronic device. You are in violation of penal code 475J-1300. Place your hands above your head as you spread out face down on the floor. Do not move or you will be obliterated. You have 5 seconds to comply."

We all know the hours Dale Robinson spent on just heads of his 450 HP Olds 307. The Procomp heads would need the sh*t milled out of them as would the suggested W30 heads. Pretty sure 198cc runners, not sure why Edelbrock/Procomp says they are 188cc. The new Edelbrock are 215cc intake, perfect for a 307🤥. This post is funny.
 
There goes the price of W30 heads!!

Dont need no stinken W30 heads.

I have what has to be the worst combination of Olds 455 parts known to man. My 455 does make around 425-450hp. Where was all this good engine building suggestion when I needed it? lol
