What size carb is everyone running on their 383

[RustyRatRod]

I just picked up a 3310 Holley, reading a Holley sheet on it, they said was designed for a Chevy 396, and they are 780 cfm , looking forward to building it , good morning

Mike, it it has a metering block in the back like in the front, it's a 780. If not, it's a universal aftermarket 750. If you post a picture, we can tell you.

Hell, that high didn't last long, my 50 dollar Holley is a replacement, no metering block on both ends , but a good carb to rebuild and put on the shelf I guess, manual chock also

Now worries Mike. It's still a DAMN good carburetor! And if you want to convert it, it's REAL easy. Plus, IT'S ON SALE!!!!! LOL

Update. Thanks everyone for the replies. I found a Holley street dominator intake on marketplace. I showed my wife and went to work. I came home to find out she contacted the seller researched the part number and went and picked it up for me. I came home from work to a big smile and my intake. What a great wife! Im leaning towards the Holley 750 vacuum secondary now.

I’d say if you know the TQ and can tune it go with it otherwise it’s the 750vs Holley, just spend some time tuning AF and secondary opening.
