Differences in Holley carbs
Ok Holley 4492 is for 70 l78/ls6 auto and 4557 is for 70 l78/ls6 4 speed. What differences between the auto carb and the 4 speed carb? Can the 4 speed carb be used on an auto car and vice versa?

The auto carbs usually have a pump squirter which is 2 sizes larger than the Manual trans cars... it is to help the car get over the Torque converter.
