Who builds the fastest Q-jet

Re/ the issue of differences between carb cores- I had two carbs done five years back with identical jetting, hangers, rods by another "name" builder.
On the dyno, one made 6 hp more than the other on back to back pulls.
This year, I've sent a carb to Danny Ashley for updating and the latest improvements. Danny was great to deal with, spent time going over every detail on the phone and has a tremendous base of knowledge. He has a test engine he can setup the carb on to confirm idle speed, etc When the carb came back I didn't recognize it, looked like a new carb! Instructions and info on setup were supplied, even a spare rod clip and hanger screw! You could not ask for a nicer guy or for better service!
I'll be dyno testing it next month , but for sure expect the new carb will be easier to drive and use less fuel in the pits/return road as the old carb had all four barrels opening together, not progessive, and was easily loading up driving under light throttle except on the track. With the old carb, I had to complete my burnout to clean up the motor before a run....

I for one would be interested to hear if the new changes netted any
more horsepower and torque . Also like you said, did the changes improve the driveability . ed
