Was this originally a 750 cfm Q jet and you ground the rings off, changed the booster design and milled out the ring in the venturi and it still wasn’t as good as the stock 71? So was the WOT better than the 71? What do you use to get inside there to grind that ridge out? Do you think taking the ridge out it lost velocity? Thanks!

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
