I run split quadrajets on propane
I have had great luck with the Quickfuel carbs on my boat never had any trouble with them. are they the best who knows they work
great for me . i have herd good things about the pro fuel carbs
You'll get lots of opinions on this topic...here's mine. When we were racing drag cars (SBC/glide throttle stopped to a 10.90 index), we started with an OLD 850 from the Carb Shop in Ontario CA (built before the original owner passed) and it was a basic hot rodded 850 and worked great. Over the years, I got talked into trying several botique carbs from a few big name suppliers. All were supposed to be built to our "exact" combination, with lots of big claims and ALL were a disappointment. Most made a bit more top end power (a couple MPH), but struggled with the on/off throttle from the throttle stop. Also, they also tended to run crappy around the pits regardless of tune up. Out of desperation, we put on a stock Quick Fuel 850 on the car, It worked fantastic right out of the box!! No significant top end loss but regained the consistancy we had lost with the high dollar carbs.
A buddy that also raced fast SBC's opinion is most of these carb builders were focused on big block combo's and really don't understand SBC's. The fact that a lot of the positive comments on the suppliers I used were from big block racers suggests he might be right.
The only way I'd ever do another custom carb(s) with a $$ back guarentee that their stuff does what they claim it will or they get it back. Otherwise I'm going to use stock Holley HP's or Quickfuel carbs.
OBTW, though I've never tried them, the guy that does our dyno work speaks very highly of Proform Carbs. He's used them on lots of different combos from street to fast brackets and says he's always able to get a good tune up out of them.
As with anything racing/hot rodding related, YMMV.
Pro systems does not massage over a shelf Holley.
They select the throttle plate, main body, boosters, metering blocks ect individually for the specific engine in a specific vehicle. Blueprint everything flow test provide build sheets with rich to lean jetting info.
And.. If you put the carb on something different, Pat will provide everything needed to make it work.

From what I've seen the guys at Pro Systems are extremely sharp. http://www.pro-system.com/
cyclone has a quickfuel carb i think.

John likes to build his own stuff but If I bring him this one I will save like $250-300 bucks ! Probably just bug him w/ this tomorrow. I'm just bored on graveyard shift !
