If you don't use a choke, check out the Holley Days sale on the Quick Fuel "Brawler" 950. Don't freak about them calling it a 950 because the venturi size is only 1.45" vs 1.56" for a 4781. IIRC, the sale price is about $520 right now. It's Quick Fuel's version of the Proform 950, FWIW. That sounds like the hot ticket for ya Belvedere1. I would suggest a 950 4150 carb for your combo. If you have the extra money a 950 from Thumper would be the best way to go. If you don't want to go that route you can buy a carb custom built to your combo. The last time I bought a custom Quickfuel from Summit Racing I don't even think there was any extra charge for it money wise. You just fill out a form and they order it, this was several years ago though. The custom carbs I've used have been spot on, just bolt them on and enjoy your car. The 950 ProSystems carb on my current Duster, I bought it used on Racingjunk. Turns out the thing was only 2 weeks old because his customer wanted efi, and the guy selling it used to work for Prosytems, so he even set it up for my combo, and it runs like perfection. So you can find good deals out there, you just have to hope they haven't messed with the carb much.

I'll check that Quick Fuel out. They have some great deals going right now through that sale which is what boosted my motivation to look at making a change. I would like to get Thumper's input on either putting one together or tweaking one that I buy. Every carb sent to me even new in the box need work and some more than others. $500 doesn't get ya much imo but try one of those mentioned and see how it works out for ya but I'd at least take it apart and make sure the tech carb matches the carb cos you'd be surprised how many don't...........

Do jets, floats, gaskets, power valves, air bleeds, etc interchange between the Holley and Quick Fuel carbs?

Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Give me your thoughts on this QFT based SQ-950. I can get this built to my specs but this a starting point.
It has been assembled with high-flow .110" needle & seat assemblies, 30cc pumps, #33 squirters with pink #330 racing pump cams, non-stick bowl and block gaskets, nylon bowl screw gaskets, and vent baffle. The jetting is 78 up front with a 6.5" Hg high-flow power valve, and 86 in the rear with the power valve circuit blocked. The mounting gaskets are included as shown. Here's a list of features; QFT polished lightweight aluminum main body with screw-in air bleeds. .073" idle and .030" high speed bleeds installed. Red anodized billet aluminum metering blocks that are custom calibrated for maximum performance. 4 corner idle for fine tuning your idle circuit. Teflon coated throttle shafts, stainless steel throttle blades, and loctited button-head screws for increased flow due to decreased turbulence.

Have them put in .120 cos .110 are not "high flowing" and need more pressure to be stable like 7 psi instead of 6 or less w/the .120`s...........

I'd want to know what QF uses as an out-of-the-box tune in order to see how much "custom calibration" is really done to a carb built to "your" specs. Wouldn't be the first time I've heard about "custom calibrated" carbs being about 95% out-of-the-box, and part of the 5% difference includes the decals for the shop that sells it. Yeah, I'm pretty jaded these days.

It shouldn't be that difficult to compare what is in a box stock SQ-950 to the changes that would be made. I'm still in research mode on the whole thing. I hope to have something figured out in the next couple of days. I was very happy with my QTF carb they set up for me.. it was a E-85 carb and they did a fine job.. they asked a bunch of questions and when I put it on the car it was on the money even with the AF meter on it.. even the idle
