Take your glasses off!! Correction in print: 440's are superior to 413's in SOME ways, 440's have their place on the street and the track, and so do 413's, youngster. Repeating, if there were no Ram-Induction, Max-Wedges or, Cross-Rams, there would be no Magnums, Commandos or Six Barrel/Six Packs. "RBs", and even some standard "B" mills, were weaned on hi-performance, multi-carb technology ("old school science").
