Yeah I get what ya mean, when I visited Clifford it does read that way for sure. I headed over to Tom Langdon's in their tech articles it explains stuff a bit more talks about those motors accepting a 254°-264°cam without any poor affect on gas mileage. Langdonsstovebolt.com-tech tips-carbs & cams great info on that site. I wonder with the portion if it has anything to do with the siamesed ports?
