I'm talking the opposite of the way you may think. I want one that would allow a Q jet to be used on a Square bore manifold. My friends are building an RX7 with a 350 and are trying to complete it as quickly as possible and on a $2000 budget cause my friend leaves for college end of the month. Well I designed the motor with a Comp Cams XE268H, Edelbrock Performer RPM intake, guideplates, home port work, and roller rockers. I want them to put an Edelbrock Performer 600 carb on top but they are deciding to go with the Qjet for now.
