the 4 door frames are longer.
You will need the 2 door frame from 68-72 Skylark or the others mentioned above. The convertible frame is boxed in the center section to help it with strength, so you...

You are wanting a 67 core?

Yes, most all of the "big shop" reman shops do butcher work on any quadrajet they get. They set them up for generic use and they are meant for specific engine use.

Take valve cover off and watch for valve movement while turning engine over.

Forgot to add, if you are doing this yourself, make sure you get your parts from cliffshighperformance.com

original jets were 68 and you can go up a size and replace the primary rods. You will...

Hi Jake.
in my opinion, you are better off with your build to work from the Buick 350 Quadrajet. Anywhere from 70-74 for divorced choke or 75-76 year if you wanted electric choke. These carbs are...

Sorry I missed this.
you may also need to replace the base plate for larger throttle blades. You are correct, you can use the metering blocks and bowls on different body.

Anna, several issues can be causing this, and certainly possible for your carb to be an issue. Vacuum leaks can cause poor idle and dying/sputtering especially when applying your brakes if you have...

For parts, check with Cliffshighperformance.com. You would need to call them. Or quadrajetparts.com

I use hydraulic lifters in all of mine. If you choose to go roller, lifter girdle is necessary.

oil mods can be done with good quality drill. They are pretty much self guiding.

The 73 is a good block to work from. Make sure proper oil system modifications are done.
i run stock crank and rods in my 455's with one dyno test at 648 rear wheel hp. That engine has edelbrock...

Yes, post a picture.
the Quadrajet was introduced in 1966. You may have a 4 jet carburetor, the predecessor to the Quadrajet.

some parts are still available for the 4 jets.

I have run Valvoline racing oil for many years with excellent results.

your HP guess. Who knows. Numbers are just numbers. Tuning can make a huge difference. 800 cfm Quadrajet would help you.

Welcome to the group.

There are instruction videos available for top replacement. I have not tried it, and after hearing advice from those that had tried it, I decided not to try it myself and let a shop do it.

Quadrajet builds are what I do. Specializing in the Buick Quadrajets.

www.quadrajetpower.com is my website with information on what I do in a build. I...

haha, yea, that's me.
Hope you get your engine figured out. And that Quadrajet can be set up to work with just about anything you want to do with that 455.

For a 71 455 you would be much better off with a 71-74 Buick 455 Quadrajet. This design is 800 cfm and has many improvements in design from the 67 8 or 9 quadrajets.

If you need an electric...

You can run a Quadrajet either with an adapter or you could find the quadrajet intake.

Stock Buick 4 barrel intake manifold or TA aluminum intake. Similar in performance but TA aluminum is lighter.

Quadrajet. Built for you Buick 350. 750 cfm and you could choose divorced choke,...

Merry Christmas

Monte Carlo is a good donor car for disc. Or other GM a body 70-72. Pretty limited.

I set up one car with used spindles and stuff. On my next car, I went to eBay and bought a complete kit. It...

Nice wagon. I like that.

Ok, I guess if you have what you want you don't need any help.

I personally like the fact that a quadrajet can deliver the cfm the engine desires. It's not all or none, like most others. With...

I have not had that happen, but I have heard of it. Everything running ok before it happened? You should check and make sure the distributor still moves smoothly. And you can replace the...

Ok Colin, you can disagree on cfm if you want.

first rule I learned when I started working on Buicks was to toss out all my Chevy building knowledge. Buick is a complete different engine design...
