I'm just about to fit a new holley 390 to my '55 292 and I'm not sure how to connect the original throttle linkage. The new carb has the modern BIG hole connection in the throttle lever and the original (threaded) rod is small. I had assumed maybe to use a small lower hole on the lever but am worried this might lead to a jerky throttle action. Can I ask what others have done?

Cheers
