It depends on what engine option you have. If you have a 'base' 350 engine, an Edelbrock Quadra-jet carb will fit fine; it has the small primary/large secondary throttle plates like the original carb. If you have an LT-1 or optional BB engine, they came with Holley carbs from the factory. The intake openings in the manifold should tell you which type carb to get.

Hi W,
Holley makes a spread bore carb that's a direct fit. It's a single feed, double pump, with mech. or vac. secondaries. Some people aren't crazy about it, but I've really liked it over the years.
I think it makes the engine look more serious than it actually is.
Regards,
Alan

I dumped the lazy Q-Jet on my 68 427/390 and went with this carb (mechanical secondaries) It really woke the car up. Great carb once I cleaned out the metal shavings

Translation: My Quadrajet was malfunctioning/ not tuned right, so instead of fixing it, I downgraded to a Holley.
Metal shavings in your carb, yet another Holley exclusive!

The metal shavings aren't unique to Holleys.

Unless the rebuilder did not know what he was doing, a rebuilt carb IS a new carb.
Sorry, I have been rebuilding carbs for over thirty years and have yet to find metal shavings in one. I have, however heard several similar horror stories about things people have found with their new (last ten years) Holley products.

Sensei, I guess we'll have to agree to disagree

Demon carbs are actually quite famous for coming full of shavings, although I think they have gotten better lately.
