Doooo What......
Well everyone has heard the old "Doooo What" from ther Quadrajet when they stand on the gas.
I bought a Stage 2 Quadrajet from SMI, and the "Doooo What" is gone.
My old carb was totally worn out, bushings etc, and needed a rebuild.
I just decided to get a new unit, and man does it work.
My 71 Nova has a 327 with a little above stock cam and normal bolt ons, and a LT1 style T-56.
The car pulls hard, with no hesitation in any gear, and idles along on the highway in top gear.
Without a doubt, this was a good modification.

Going from the small primaries and tipping in those larger secondaries, there is a huge onrush of air that needs fuel to keep it from leaning and giving that Dooo-what. Apparently your new carb has been worked over to provide a good transition when your foot is planted in the carb.
1970 RS/SS350 139K on the clock:
89 TPI motor w/ 1pc rear seal coupled to a Viper T56 via Mcleod's modular bellhousing w/ hydraulic T/O bearing from the Viper, 12 bolt rear w/ 3.73 gearing, SC&C upper control arms, factory lowers with Delalums, C5 brakes at all four corners, Front Wheels 17x8's with Sumi 255/40/17 and Rear Wheels 17x9's with Sumi 275/40/17.
