Got my June (!!) issue of Car Craft over the weekend. They tested 19 intake manifolds for a small block Chevrolet, and reported peak horsepower, peak torque, and average torque on a 500+ horsepower engine. Sounds vaguely familiar
, but all 19 manifolds were single plane, 4150 single carburetor intakes, and all are available right now. Talk about selection! Sometimes I'm shocked at the difference between the FE world and the SBC world...
