Question Quick Fuel Carb Opinions Needed

I,m building a 69 Camaro Drag car with a 406 roller motor, Pro Action 235 runner heads, 13.5 :1 compression.Callies bottom end, Running a glide with 5:13 gears. Its tubbed with a glass nose, not sure on the weight.Probably shift at 6800-7000 rpm range. My question is what cfm carb would best fit my needs. It will be mainly 1/4 mile runs, a few 1/8 mile tracks.I.m looking at the QuickFuel Pro 850, What do you guys think?

The Quickfuel 850 has a 1.425" or 1.450" venturii with a 1.75" butterfly

It would work good, i had one here a while ago, im leaning to say it was a 1.45" venturii but it may have been 1.425", its one of the two, cant recall off the top of my head

Call and talk to Zach, Marvin or Marty @ Quickfuel

To give you some insight, we have a 1980 camaro with a 406, specs below
-406 bored with KB hypers with two valve reliefs {flat top}
-283 heads, bowl ported, larger 2.02/1.6 valves installed, cut for 1.46" springs and milled to get compression @ 11.5:1
-Solid flat tappet cam 256/264 @.050 .545/.563 105° lobe seperation installed at 102°
-Victor Jr. manifold
-850 BG modified by us
-powerglide with transbrake and 4,500rpm stall
-12 bolt rear now with 4.88 gears with 32" rear tires

Exact car weight is 2,780 pounds with driver after the run, fiberglass front clip and more
Best ET 10.436 @127.4mph
We shift at 6,000rpm and run 6,500rpm past the lights - it has many 10.43-10.49 passes thus far and we have a little more

We started at 10.88-10.92 and have tuned down to 10.615 with tune ups, we then installed 4.88 gears in place of 4.56's 10.436-10.49 passes, warm up pass is always in the 10.50's

If you would like a link to the thread on our camaro i will post it for you

If you're going with the QFT line, would recommend a QFT-P-1050 and an Edelbrock 2970 (Super-Victor 4500) with those RHS 235's.

The last similar setup left here with the above parts and some 2.000" "Stahl" primaries for pipes. Same heads but 11:1 C.R.

Came off the dyno with 580+ HP @ 6700 (this was the "delivered" number, we made 600+ in the dyno room with some very minor changes for our own testing) and 520#+ Torque @ 5700 using 93 octane!!

Had a relatively "small" solid-roller cam inside also, a 256*/264* @ .050". I would assume here you've got a somewhat better "cam" in there with that C.R.

This is presently in a 3600#+ El Camino and runs in the 124/125 MPH range, still on 93!! Last time out he needed a convertor change, was running 11.0's at those MPH's.

Those heads have given us some "very-serious" HP numbers, with a minimum amount of time involved, on other units! We've had some very good numbers with that entire line of heads over the years. Have many BB's here always!

(Add) If you're using an "OEM" 400 block, you can subtract 20/30 HP from the platform over using an aftermarket block. These OEM blocks "lose" that much! Would expect to see in the neighborhood of 700 HP (guesstimated, not having all your specs available) with your build along with some decent torque numbers with that C.R.!

Thanks, Gary in N.Y.

P.S. The "QFT" carbs are some of the best we've worked around!! Normally have about a dozen or so here most times.

Wow, was'nt expecting the 1050. I allready bought a 4150 Hurricane intake so now what ? P-950 ? Yea, the cam will be a little bigger than what you described, but have not had it cut yet. Open to any good advice. thanks

Save yourself a lot of confusion and call Quickfuel. They are really sharp, and will get you the right carb the first time!
You don't have to buy a super high dollar carb to go fast. I have a Bishoff racing engines 565 BBC, 14 to 1 compression. In a 3630 pound 70 SS it has gone 9.57 at 138 MPH, 1.32 60 foot. It has a $600.00 Quickfuel Q950 on it. I took it out of the box, blocked the power valve (personal preference), and square jetted it. Nothing else. These guys ROCK!!!

Nathan , i would say the 850 is the way to go . That engine could swallow the 1050 ,BUT i dont think it will like the glide as much as the 850 . Have you thought about annular boosters ? I like them .some don't.

Nathan, how's set up doing? Just saw your post had to comment. I have a 67 camaro setup pretty much exactly like yours. I a stock block with hard block, victor Jr heads that I ported, 260/264@.050 roller and I used my quick fuel 1050 alcohol dominator for lack of a proper sized one and it ran 6.48 at altitude which is about a tenth better than my last 406 at that track and it 10.02@132! I'm putting a QFT 950 with the 1.45 Venturi and can't wait to try it, should be a solid 9 second car. Good luck with your's and let us know how it went.
Keith

The Dominator will usually be faster if you have sufficient stall which is dependent on what you have for a cam. As far as the 4150 carbs, all the Holley 850's and 1000 CFM carbs have the same venturi and throttle blade size, and flow similar. The 950 Holley is a joke as far as size, it actually flows around 830. 750 main body with an 850 baseplate. Since you already have the 4150 intake, try this carb instead.

I love my QFT 850. Took it out of the box, adjusted the idle, and it is very impressive. A little fine tuning and ill be done. I am very happy with it on my BBC.

QF P-1050 3 circuit Dominator works great for me. I did a couple mods since the car drives mostly on the street. I switched to progressive linkage from 1:1 and put a power valve in the primary. LM-1 shows a bit rich at cruise but w.o.t. it high 12s.
No bad manners at all. Plugs look good.
