I have been driving my 67 vert with the four- hundred four speed with a rebuilt carb from a 1968 buick with an automatic. That's the closest I could find for the motor when I was having it installed. Motor was built to factory specs. I have since located the proper carb for a 1967 with standard transmission and what a difference. The car really wants to go now. I didn't realize how much of a change it made to have the proper carb on your car.
