Absolutely! I recommend starting with 68 jets for a Holley 650, then adjusting as you monitor performance. Different conditions can require different settings.
I’ve been using a Holley with a 750 cfm rating; it’s a bit overkill for my 350 but gives me some serious throttle response. Has anyone experimented with tuning for better fuel economy without losing performance?

Great question! You can try leaning out the jets slightly for better economy. Just be cautious not to go too lean, or you might risk engine knock.
Hydraulic lifters or solid lifters can also affect tuning. If using solid lifters, ensure your engine is at the right RPM to avoid running too rich or lean when it matters most.
That’s interesting, williamsdanny! But how do solid lifters impact carburetor tuning specifically? I thought it was mostly the balance of air-fuel mixture that matters.
The valve timing and lift change with solid lifters, which can affect how efficiently the carburetor feeds the engine. Adjustments may be necessary to maintain performance.
Consider adding an adjustable fuel pressure regulator if you’re serious about tuning. This can help you get even more specific with your adjustments and ensure you’re getting the best performance.
That’s a good tip! Fuel pressure can have a significant impact on performance. It’s a game-changer if you’re modifying your setup.
I see a lot of people arguing about the best carburetor choice! Isn’t it really about the specific application and driving style? A Holley might suit one setup, while an Edelbrock fits another better.
Exactly! Each engine responds differently to tuning, and personal preference plays a big role. It’s all about trial and error.
When tuning, don’t forget to check the air filter! A clogged filter can suffocate your performance. Keeping it clean will help ensure you get maximum airflow to your carburetor.

Yes! It’s the little things that can derail your whole setup. I’ve had issues and didn’t realize until it was too late!
Just keep in mind that tuning can also be an art. It sometimes requires a bit of patience and experimentation to truly find that sweet spot for your specific Chevy.
I’ve had great success with the Edelbrock Performer 1406 on my 350 Chevy. Installation was straightforward, just make sure you have the right gasket set.
That’s awesome! How was the tuning process? I struggle with getting that just right.
Definitely check your float adjustment. If it’s off, you could face flooding issues or lean conditions. I had that happen before.
Great tip! I also heard that using a fuel pressure regulator can help maintain consistent pressure.
I had a bad experience with a Holley carb. Had to troubleshoot a vacuum leak for weeks. Make sure all your connections are snug!
That’s good to know. I’ve considered Holley, but I’m leaning towards Edelbrock. How about you, any particular reason for switching?
I love the sound of a 350 with a good carb on it! I went with a Quick Fuel Technology carb, and my engine has never run better. Super easy to install too!
