I’m about to list an Offenhauser 6226-C with Weber carb and Clifford 4bbl to 2bbl adapter on Mud. I pulled it off my nicely running 1981 so I could go back to the stock setup. Figured this might be the best way to get every bit of HP you can out of your 2F - especially if coupled with EFI. Everything was running fine when Marshall pulled it out. $400
