Q jet for sure. Have yours rebuilt or check out the one listed on here for sale, it looks like a great deal and is a direct bolt on for your 275 H.P., 327 with Powerful Glide. Nothing beats a Q jet for all around economy and performance. And no, I don't have anything to do with the one listed for sale!!
When you lift off your carb, have a look at the intake, there may be 2 small ports 1/4" at the front of the intake that are exhaust ports that are meant to warm the carb,,,, BUT?.. You have to run the correct carb , or may have vacuum issues, and poor performance.
the work around is to tap 1/4 pipe plugs into these riser holes...blocking the exhaust port, that way you can run whatever carb you want...
just saying...

I'm assuming you have an original 327. This one listed even comes with the proper carb. gasket/steel shim required for a 1969 and older intake like rabbit64cs mentioned. Post some pictures of your engine/carb/intake to be sure.
I ran the stock Quadrajet on my 67 327/275. I had it pro rebuilt, and I can say it worked flawlessly. I don't think any other carb would have produced the same performance on that motor. I'm running an Edelbrock 1405 on my 350, and I'm willing to bet a QJet, set up properly, could best the Edlelbrocks numbers.
Unless you're going for a intake change as well, I'd definitely stick with a QJet.
There can be more than a few reasons for fouled plugs. But a rebuilt carb, along with a complete refresh of the ignition side would probably help you.

Q-jets can leaks fuel and may need to be professional rebuilt, only way to go.
Used to rebuild carbs, there is a well on the Q-Jet (middle underneath), that can leak fuel.
We used to epoxy them. Can't remember what I used though.
The Q-Jet is a great carb. (I happen to use a Holley these days though).
Thanks for all the help thus far
I'm learning a lot reading everyone's posts.
When I get home tonight I will take some pics and post them.
How can I do that is there directions on the site to do this?
Good pictures. Your carb and intake look like 1967 stuff but your heads are 1969 or newer. Not that it matters but the engine might not be a 327, could be a 307, 327, 350 or something else. The other carb listed should be fine but you will have to hook it up properly. You have the choke vacuum break, or pull off unhooked, unless it's a double port, and that will cause flooding and black smoke until the engine warms up. Your carb actually looks pretty good and could probably be rebuilt if you can find someone who knows how. Many 1967's are all cobbled together with red heater hoses, yellow plug wires, backwards valve covers and chrome do dads, but yours looks pretty good!! Even a new carb won't be any good if you have other problems, low compression, flat cam etc. so hopefully your not overlooking normal tune up stuff.
Thanks Randy
I don't know the person selling the other carb, but if it's the actual one in the picture it looks very good. Maybe someone on here knows the seller??

Even though I hugely support Qjets, I have to agree with Shawn, my 327 I put in the 65 Acadian before I sold it ran beautiful with a 600 Holley on it.
I bought that carb brand new out of a place in the US for about $240. It was a screaming good deal, I was real happy with it. I would have used a Qjet but the 69 Z28 intake I used was designed for a Holley.

For sure any kind of carb can run good, I just don't see the logic in not running the best available when possible.
A Q jet in good working order will outperform a 600 Holley in every respect.
If the engine uses oil it will plug the intake exaust crossover port and then there is no heat to the choke stove and the choke will stay on. Also heat riser valve may be stuck open, and the choke pull off is unhooked. These things will make lots of black smoke. Major hard on fuel also.
CNN tells me this is a rare news vehicle engine, LOL
Actually its a 1970, 350, 2 bbl, 250 H.P. originally approx. 9:00 to 1 compression. That's a great engine so you're very lucky!!
In 1969 this exact combination of L-65 (250 H.P.) bottom end and L-48 (300 H.P.) intake and carb resulted in the famous L-M1(255 H.P.)
So in your opinion this is a nice
Combo someone put in the car
Sounds good to me too
That same carb I'm thinking of sending out for rebuild
Do I need to tell the carb rebuilder this info so they can calibrate it a little differently ?
And the power drop from the 327 to the 350 must be from a different cam and heads?
Not that it matters just curious
Thanks Greg
Its actually more powerful. I see engine horsepower ratings as more of a system to I.D. engines rather that their actual power. 275 H.P. 327 cylinder heads would make yours a 300 H.P. 350. There are many cases where a higher rating makes less power than one with the lower rating. EG: 300 H.P 327 is less powerful than a 275 H.P. 327 350 H.P. 327 is less powerful than a 325 H.P. 327
270 H.P. 350 is less powerful than a 255 H.P. 350
360 H.P 396 is less powerful than a 350 H.P. 396
365 H.P. 454 is less powerful than a 360 H.P. 454
Thanks Randy
