I currently have a 73 Barracuda 318 (mild build) that currently has a Street Dominator manifold with a older Holly 6R-5643B and a 7956 throttle body. All of the original pollution stuff is still on the car and good shape except the vacuum line could be replaced. The car has developed some surging at cruising speed which I believe is a vacuum leak somewhere. A coupe of questions: 1. What carb do you guys recommend? 2. Can / shall I use the original throttle body with the new carb or replace it? 3. Would you recommend removing the pollution control stuff?

Thank you.
