If you are not using a 2 step and the throttle is not to the floor the secondaries have not opened. So Back in the day (mid 70's) it took a lot of work to make the carb work right with the high pressure clutches and tires we had. Go buy a 2 step makes it easier. One less thing to worry about. Don't those chevy transmissions have a real high first gear like 2.20 or such? That is a problem also.
