I can't remember the exact info so it would be a good idea to do a search on this subject. I was looking at the same swap and I read on the board that alot of people liked the Clifford intake with a Holley 350 cfm 4 brl. People seemed to get better power and better mileage with the 4 brl. too. Someone also posted that they found the Holley/Weber ran rich at idle and lean opened up. I decided on the 4 brl., but have not had the time to do the install yet so I couldn't give you any specifics. Good luck.
