Hello fellow car enthusiasts! I’m diving into a project involving my Chevrolet vehicle with a Vortec 4.3 engine and I’ve been considering an upgrade to the carburetor intake. I’m hoping to get some insights and advice from those who have experience with this setup.

What I’m Looking For:

  • Best Carburetor Options: What carburetors give you the best performance for the Vortec 4.3?
  • Intake Recommendations: Are there specific intake manifolds that work particularly well?
  • Installation Tips: Any advice on installation or common pitfalls?
  • Performance Gains: For those who have done this modifications, what kind of performance improvements did you notice?

Why I’m Upgrading:

I’m looking to improve the overall performance and reliability of my engine. I’ve done some research, but I find that personal experiences shared in forums often have the most valuable insights. So, what systems seem to blend well with the Vortec 4.3?

Additional Questions:

  • Compatibility: Are there certain brands that are known for better compatibility with this engine?
  • Costs: What should I expect to spend on a decent carb intake setup?

If you’re looking for a solid carb intake for the Vortec 4.3, I’d recommend the Edelbrock Performer 600. It offers great performance and is known for its drivability and efficiency at lower RPMs.

That’s a great suggestion! I’ve had good experiences with the Holley 390 as well. It provides a nice balance of power and fuel efficiency.

It’s also important to tune the carb correctly. I’ve noticed a massive difference with proper tuning; it can really enhance drivability.

Absolutely! Proper tuning can make or break your setup. Don’t forget to consider the type of driving you do most often.

What is the main goal for your build? If it’s performance, the Holley might edge out the Edelbrock, but for daily drivability, Edelbrock is hard to beat.

That’s true, but I find the Edelbrock provides smoother acceleration with a more consistent power band, especially for street driving.

I’ve read mixed reviews about the Holley setups. Some love them, others mention issues with tuning. Have you guys had any personal experiences?

I totally agree! My buddy had a rough time with his Holley. But when it works well, it’s hard to beat its power!

I’m leaning toward the Edelbrock for reliability and ease of tuning, given my limited experience. Recommendations for jet sizes would also be appreciated.

For starters, if you go with Edelbrock, I’d suggest a 0.100 main jet initially. Adjust from there based on your driving style.

Don’t forget to factor in the cost of setup! Sometimes cheaper doesn’t always mean better performance. Budget wisely!

That’s a great point! But we all love a good deal—who can blame us for trying?

14

This all sounds great, but can’t we just slap on a new intake and call it a day? I mean, how hard can it be? Right?

15

Haha! If only it were that simple! Every engine is a bit of a diva, needing the right pampering!

I’m planning to convert my Vortec 4.3 and am looking for intake manifold options. Anyone have experiences with the Edelbrock Performer intake?

17

I used the Edelbrock Performer on my previous 4.3, and it worked great! Good power increase and easy installation. Just watch the clearance under the hood.

18

The Edelbrock Performer is nice, but I’ve heard mixed reviews about the Holley intake. Anyone know why? Is it worth the hassle?

The Holley can be great, but it’s picky about tuning. If you’re up for it, it can deliver a solid performance bump with the right setup!

I’ve been looking into this too! Have you guys considered a marine intake? They might offer good options for the Vortec 4.3.
