Re: Same quadrajet instead of double pumper holley???

This much I can say, the Q-jet will be a pita to properly jet to your new engine. You almost need a master’s degree. I pulled my Q-jet off and put my old 4150 on with a 1” spacer what difference, I also put an electric choke kit on it and new jets and power valves , so easy to tune. So this is just my 2cents, good luck!
