I never tried the q-jet. Back in the '60's I picked up a '62 Olds F85 Jetfire. It had a single barrel Rochester If I remember right. I discovered that the shaft between the boost control diaphram and valve was covered by a piece of tubing, so I drilled the tubing and shaft and put a cotter pin through it to hold the valve closed. The thing was a Rocket. Blew off a 327 Chevelle and a single carb Goat before one of the pistons went out the tailpipe. It's surprizing when you have something sucking real hard on a carb how much more they flow.
