Need Help with 350 Big Block Engine Upgrades!

Accessories & Modifications
1

I’ve recently picked up a project car, and it features a 350 big block engine that I’m super excited about. I’m looking for advice on a few things:

Engine Specifications

What are the essential specs I should know about this engine? Are there common performance tweaks that can help boost horsepower and torque without breaking the bank?

Aftermarket Parts

I’d love recommendations on reliable aftermarket parts. Which brands do you all trust for performance upgrades like intakes, exhaust systems, or camshafts?

Installation Guides

If you’ve done any upgrades or installations yourself, I would appreciate any guides or tips you could share. What were some common pitfalls you faced?

Comparisons with Other Engines

How does the 350 big block compare with similar engines, like the 454 or other small blocks? Any insights on which one is better for specific applications?

Any help or direction would be greatly appreciated! Looking forward to tapping into the collective knowledge here.

I’m looking to max out my 350 big block’s potential too! I’ve heard that swapping to a performance intake manifold can really open things up. Any recommendations?

3

Absolutely! A Holley or Edelbrock intake manifold can greatly enhance airflow. It’s one of the first upgrades I recommend for better torque and horsepower.

4

Don’t forget about exhaust upgrades! A nice set of headers can drastically improve performance, not to mention the sound is unbeatable!

5

So true! I paired mine with a dual exhaust system, and the difference in throttle response was incredible.

6

Is there a specific tuning strategy you can follow after upgrading your intake and exhaust? I want to ensure I get the most out of my enhancements.

7

Definitely! Using a quality EFI system or tuning with a programmer can help you fine-tune the air-fuel mixture.

Don’t overlook the importance of a good carburetor setup too! A properly sized carb matched to your engine’s needs can really unleash power.

That’s a solid point, @wcastillo! I’ve noticed that a functioning and properly adjusted carburetor has made a huge difference in my setup.

Has anyone tried performance camshafts? I’m curious about how that impacts overall performance on the 350.

11

A performance cam can make a huge difference! It changes the engine’s power band and can give you that extra power up top.

12

Make sure to consider the entire system too! Don’t just slap on parts without thinking about compatibility—a balanced setup is key.

13

Exactly! It’s like putting a racing spoiler on a minivan. You need everything to work together for the best results.

14

What about ignition upgrades? I’ve read that a good ignition system can help unleash the full potential of performance parts.

15

Great point! Upgrading your ignition system can improve combustion efficiency, which is crucial after adding performance parts.

16

Hey everyone! I’m considering upgrades for my 350 big block engine due to overheating issues. Any advice would be appreciated!

17

You might want to check your radiator and thermostat first. They are common culprits for overheating in big blocks.

18

I had an overheating problem, and it turned out to be a clogged radiator. Flushing it fixed the issue. Don’t overlook that!

19

That’s great advice! I’ve also found that upgrading the water pump can help with cooling.

Upgrading to a high-performance water pump made a noticeable difference in my truck’s cooling. It’s worth considering!
